Weatherscope Weatherscope Application Information: Weatherscope Is a Stand-Alone Application That Makes Viewing Weather Data Easier User Guide - Macintosh http://earthstorm.ocs.ou.edu WeatherScope WeatherScope Application Information: WeatherScope is a stand-alone application that makes viewing weather data easier. To run WeatherScope, Mac OS X version 10.3.7, a minimum of 512MB of RAM, and an accelerated graphics card with 32MB of VRAM are required. WeatherScope is distributed freely for noncommercial and educational use and can be used on both Apple Macintosh and Windows operating systems. How do I Download WeatherScope? To download the application, go to http://earthstorm.ocs.ou.edu, select Data, Software, Download, or go to http://www. ocs.ou.edu/software. There will be three options: WeatherBuddy, WeatherScope, and WxScope Plugin. You will want to choose WeatherScope. There are two options under the application: Macintosh or Windows. Choose Macintosh to download the application. The installation wizard will automatically save to your desktop. Go to your desktop and double click on the icon that says WeatherScope- x.x.x.pkg. Several dialog messages will appear. The fi rst message will inform you that you are about to install the application. The next message tells you about computer system requirements in order to download the application. The following message is the Software License Agreement. It is strongly suggested that you read this agreement. If you agree, click Agree. If you do not agree, click Disagree and the software will not be installed onto your computer. The next message asks you to select a destination drive (usually your hard drive). The setup will run and install the software on your computer. You may then press Close. You are now ready to view Oklahoma Mesonet, NEXRAD radar data, and National Weather Service data on your computer! How do I Use WeatherScope? There are several shortcuts to make using WeatherScope easier. To Zoom In, click the mouse button on the map. To Zoom Out, hold the Option key and click with the mouse. To move the map, hold the Apple key and drag with the mouse. When WeatherScope is fi rst opened, you are provided with a blank map of Oklahoma. To add another state to the map, choose Product, New, Shape. http://earthstorm.ocs.ou.edu Then choose a state from the Region pull-down menu. While in this dialog box, you can choose a Feature, such as county borders. Then click OK. To add a radar to a map, choose Product, New, Radar. There are many radars to choose from, so to narrow your choices, there is a Filter feature. Type in a few letters of the site you are interested in (e.g., MO for Missouri radars) and the list will be limited to radars with those letters in their name. Then choose your desired radar site. Below that is a list of Radar Products. Base Reflectivity I is the most used radar product. Once all options are selected, click OK. To add National Weather Service Surface Observations to a map, click Product, New, Observation. A dialog box will appear. Choose NWS Surface Observations from Data Set. There is a long list of variables, and you can enter a few letters of a variable in the Filter to narrow down the list. If you choose Air Temperature, make sure to check the Units. You can choose from degrees Celsius, degrees Fahrenheit, or Kelvin. You can also choose the color of the label, as well as the position relative to the weather station. To animate the data or select a different date or time, double click on the Date and Time stamp at the top of the legend. A dialog box will appear and you will be able to select the date and time you wish to animate. You can then choose how many minutes, hours, or days to loop through, whether you want it before or after the selected date, and if you want it to sync to a specific data set or step by a certain time frame. To animate the data, go to Window, Show Animator. A box will appear with buttons much like those on a VCR. Press the Play button (center button on the animator box) to animate the data. There is a bar on the bottom of the animator box that will allow you to choose how fast or slow the animation loops. You can turn animation on and off from the Legend by clicking the arrow icon beneath the date and time stamp. The legend offers opportunity for extensive interaction with the map. You can put many items on a map and still move it around for your best use. Each item in the legend is considered a layer. For instance, if you have a gradient, a county border map, and Oklahoma Mesonet air temperature observations on one map, there are three layers on the map. If the gradient is the top layer, you will not be able to see anything beneath it because the gradient is not translucent by default. To move the gradient layer, select the layer and drag it with the http://earthstorm.ocs.ou.edu mouse to the bottom of the list in the legend. Layers can be rearranged in any order in the legend. To delete a layer, click on it once in the legend and tap the delete key. Each layer has additional information that can be viewed. To see the Inspector, choose Show Inspector from the Window Menu. The Inspector shows the date and time of the data, as well as the specific latitude and longitude of the cursor’s position. This “cursor tracking” also will show the exact data of the cursor location. For instance, if the cursor is on a dew point gradient, the Inspector will show the exact dew point temperature at the cursor’s location. You may want to see a map without a particular layer, but you may not want to delete that layer. Choose the layer you wish to hide and press the Control key and click with the mouse. A dialog box will appear and the first option will be Hide. Click on Hide and the layer will no longer be shown on the map. In the legend, the layer will be translucent. If you wish to show the layer again, choose it in the legend, press the Control key and click with the mouse. Click on Show in the dialog box, and the parameter will once again be visible. To change the Properties of a layer, double click with the mouse on a selected layer. The Properties dialog box will appear. Here you can change any of the properties of the layer, including the data set. If you like the way your map looks and think you would use your chosen setup on a regular basis, choose File, Save Default. This option saves your chosen map settings so that every time you open WeatherScope in the future, these map settings will be used. Track Real Time gives you the option to either get data in real time or to turn off the feature and look at archived data. To turn Track Real Time on or off, go to Map, Track Real Time (or Stop Tracking Real Time). You can also turn this feature on and off from the Legend. Below the date and time stamp, click on the clock icon. To archive data, go to Map, Start Archiving, or click on the file icon below the date and time stamp. When archiving data, WeatherScope will save the files to your hard drive. Oklahoma Mesonet data is available back to 1994, so archiving is not necessary. However, radar data and other data types are available online for a limited time so archiving is a good idea if you wish to keep the data for future use. You can also make graphs with WeatherScope. To create a graph, go to File, New Graph. The graphs only graph Oklahoma Mesonet data and the time covers a 24-hour period. The legend works the same as in the map. For more information, please contact the Oklahoma Climatological Survey at (405) 325-2541 or e-mail at [email protected]. http://earthstorm.ocs.ou.edu WeatherScope Glossary The following are definitions for each of the product types in WeatherScope. Barb - indicates the direction and speed of wind. The barb is read from tail to tip, or the direction the wind is coming from. The sticks on the tail represent wind speed. A short stick represents 5 knots, a long stick represents 10 knots, and a flag represents 50 knots. Contour - a line on a map that joins points of equal amounts (e.g., temperature, wind speed, dew point) Gradient - color-filled map showing a rate of change of some variables across a given area Grid Lines - plots latitude and longitude lines on a map Observation - specific variable, such as temperature, wind direction and speed, of a given weather station Radar - plots radar data from a given radar site Shape - plots various shapes, including states, county borders, and highways, on a map Symbol - plots a symbol for a given weather station on a map Vector - a quantity, such as wind, completely specified by a magnitude and direction Author: Loren Gmachl - March 2005.

  • Relative Forecast Impact from Aircraft, Profiler, Rawinsonde, VAD, GPS-PW, METAR and Mesonet Observations for Hourly Assimilation in the RUC
    16.2 Relative forecast impact from aircraft, profiler, rawinsonde, VAD, GPS-PW, METAR and mesonet observations for hourly assimilation in the RUC Stan Benjamin, Brian D. Jamison, William R. Moninger, Barry Schwartz, and Thomas W. Schlatter NOAA Earth System Research Laboratory, Boulder, CO 1. Introduction A series of experiments was conducted using the Rapid Update Cycle (RUC) model/assimilation system in which various data sources were denied to assess the relative importance of the different data types for short-range (3h-12h duration) wind, temperature, and relative humidity forecasts at different vertical levels. This assessment of the value of 7 different observation data types (aircraft (AMDAR and TAMDAR), profiler, rawinsonde, VAD (velocity azimuth display) winds, GPS precipitable water, METAR, and mesonet) on short-range numerical forecasts was carried out for a 10-day period from November- December 2006. 2. Background Observation system experiments (OSEs) have been found very useful to determine the impact of particular observation types on operational NWP systems (e.g., Graham et al. 2000, Bouttier 2001, Zapotocny et al. 2002). This new study is unique in considering the effects of most of the currently assimilated high-frequency observing systems in a 1-h assimilation cycle. The previous observation impact experiments reported in Benjamin et al. (2004a) were primarily for wind profiler and only for effects on wind forecasts. This new impact study is much broader than that the previous study, now for more observation types, and for three forecast fields: wind, temperature, and moisture. Here, a set of observational sensitivity experiments (Table 1) were carried out for a recent winter period using 2007 versions of the Rapid Update Cycle assimilation system and forecast model.

  • Reading Mesonet Rain Maps
    Oklahoma’s Weather Network Lesson 2 - Rain Maps Reading Mesonet Rain Maps Estimated Lesson Time: 30 minutes Introduction Every morning when you get ready for school, you decide what you are going to wear for the day. Often you might ask your parents what the weather is like or check the weather yourself before getting dressed. Then you can decide if you will wear a t-shirt or sweater, flip-flops or rain boots. The Oklahoma Mesonet, www.mesonet.org, is a weather and climate network covering the state. The Mesonet collects measurements such as air tempera- ture, rainfall, wind speed, and wind direction, every five minutes . These mea- surements are provided free to the public online. The Mesonet has 120 remote weather stations across the state collecting data. There is at least one in every county which means there is one located near you. Our data is used by people across the state. Farmers use our data to grow their crops, and firefighters use it to help put out a fire. Emergency managers in your town use it to warn you of tornadoes, and sound the town’s sirens. Mesonet rainfall data gives a statewide view, updated every five minutes. When reading the Mesonet rainfall accumulation maps, notice each Mesonet site displays accumulated rainfall. The map also displays the National Weather Service (NWS) River Forecast Center’s rainfall estimates (in color) across Oklahoma based on radar (an instrument that can locate precipitation and its motion). For example, areas in blue have lower rainfall than areas in red or purple.

  • Multifunction Phased Array Radar
    MULTIFUNCTION PHASED ARRAY RADAR PROGRAM STATUS AND POTENTIAL SERVICE IMPROVEMENTS Prepared by: Working Group for Multifunction Phased Array Radar (WG/MPAR) August 2009 Office of the Federal Coordinator for Meteorological Services and Supporting Research (OFCM) 8455 Colesville Road, Suite 1500 Silver Spring, MD 20910 Foreword Weather radar has proven its value to the Nation since the installation of the current weather surveillance network began in 1990. In 2020, the WSR-88D radars forming this NEXRAD network will be 23 to 30 years old. In about the same time frame, most of the Nation’s aircraft surveillance radars will be nearing the end of their design life. Decisions on replacing or repairing and upgrading these National radar assets must be made over the next 10 to 15 years. We are now on the threshold of a revolution in civilian radar capability, enabled by the adaptation of established military radar technology to existing civilian applications, plus new capabilities beyond what current systems can provide. The Working Group for Multifunction Phased Array Radar (WG/MPAR) is coordinating an interagency initiative to investigate the feasibility of applying the capabilities of phased array technology to perform weather and aircraft surveillance simultaneously. This paper presents a snapshot of the status of that initiative and projects potential service improvements that would be derived from the operational application of phased array radar to aircraft and weather surveillance. I wish to thank the members of WG/MPAR—especially Dr. James (Jeff) Kimpel, Director of the National Severe Storms Laboratory (NOAA) and Mr. William Benner, Weather Processors Group Manager (FAA)—as well as the OFCM staff, especially Mr.

Our goal is to use weather observing unmanned aircraft systems (WxUAS) to perform the vertical profiles by taking measurements while ascending through the ABL and subsequently descending to the Earth’s surface. Before establishing routine profiles using a network of WxUAS stations, the climatologies of the flight locations must be studied. This was done using data from the North American Regional Reanalysis (NARR) model. To begin, NARR data accuracy was verified against radiosondes.
