  • Storms Are Thunderstorms That Produce Tornadoes, Large Hail Or Are Accompanied by High Winds
    From February 17 to 19, a severe storm blasted the Lebanese coast with 100- kilometer (60-mile) winds and dropped as much as 2 meters (7 feet) of snow on parts of the country, news sources said. Temperatures dropped to near freezing along the coast, while snowplows struggled to clear the main roadway between Beirut and Damascus. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image on February 20, 2012. Snow covers much of Lebanon, and extends across the border with Syria. Another expanse of snow occurs just north of the Syria-Jordan border. Snow in Lebanon is not uncommon, and the country is home to ski resorts. Still, this fierce storm may have been part of a larger pattern of cold weather in Europe and North Africa. References The Daily Star. (2012, February 18). Lebanon hit by extreme weather conditions. Accessed February 21, 2012. Naharnet. (2012, February 19). Storm subsides after coating Lebanon in snow. Accessed February 21, 2012. NASA image courtesy LANCE/EOSDIS MODIS Rapid Response Team at NASA GSFC. Caption by Michon Scott. Instrument: Terra - MODIS Flooding is the most common of all natural hazards. Each year, more deaths are caused by flooding than any other thunderstorm related hazard. We think this is because people tend to underestimate the force and power of water. Six inches of fast-moving water can knock you off your feet. Water 24 inches deep can carry away most automobiles. Nearly half of all flash flood deaths occur in automobiles as they are swept downstream.

Correspondence to: Guannan Geng ([email protected]) Abstract. The contribution of meteorology and emissions to long-term PM2.5 trends is critical for air quality management but has not yet been fully analyzed. Here, we used a combination of machine learning model, statistical model and chemical transport model to quantify the meteorological impacts on PM2.5 pollution during 2000–2018. Specifically, we first developed 20 a two-stage machine learning PM2.5 prediction model with a synthetic minority oversampling technique to improve the satellite-based PM2.5 estimates over highly polluted days, thus allowing us to better characterize the meteorological effects on haze events. Then we used two methods, a generalized additive model (GAM) driven by the satellite-based full-coverage daily PM2.5 retrievals as well as the Weather Research and Forecasting/Community Multiscale Air Quality (WRF/CMAQ) modelling system, to examine the meteorological contribution to PM2.5.

  • NASA FY12 Budget Estimates for Science, Earth Science Theme
    Mission Directorate: Science Theme: Earth Science Theme Overview NASA's Earth Science Theme advances knowledge of the integrated Earth system, the global atmosphere, oceans (including sea ice), land surfaces, ecosystems, and interactions between all elements, including the impacts of humans. Sustained, simultaneous observations of many quantities are needed to unravel the complexity of the global Earth system. Maintaining balance continues to be a hallmark of NASA's Earth Science Theme: Flight Programs develop satellite missions and provide observations; Research redeems the investment in flight by analyses to increase scientific understanding and identify the foci for future missions; Technology develops new measurement approaches; and Applied Sciences provides direct societal benefit by advancing the use of Earth science measurements and scientific understanding to undergird environmental policy decisions. The President's Budget advances key elements of the program established in NASA's 2010 Climate Initiative. The budget enables launch of the first two Tier 1 decadal survey missions, Soil Moisture Active-Passive (SMAP) and Ice, Cloud, and Land Elevation Satellite (ICESat)-2, by CY 2016 and expands the Venture-class competitive program with annual solicitations for facility-class instruments and alternating biannual solicitations for small missions and airborne investigations. The budget supports continued development of options for the decadal survey's Tier-1 Deformation, Ecosystem Structure, and Dynamics of Ice (DESDynI) Radar satellite. Two climate-focused Tier-2 decadal survey missions--Surface Water and Ocean Topography (SWOT) for insight into the movement and distribution of fresh surface water, and Active Sensing of Carbon dioxide Emissions over Nights, Days and Seasons (ASCENDS) for atmospheric column carbon dioxide (CO2) abundance--have been initiated for launch in 2019-2020.
