GPM) Mission Applications Examples The Global Precipitation Measurement (GPM) Mission Applications Examples Dalia Kirschbaum GPM Deputy Project Scientist for Applications [email protected] www.nasa.gov/gpm Twitter: NASA_Rain Facebook: NASA.Rain 1 Applications Overview The new generation of GPM precipitation products advance the societal applications of the data to better address the needs of the end users and their applications areas. The demonstration of value of NASA Earth science data through applications activities has rapidly become an integral piece in translating satellite data into actionable information and knowledge used to inform policy and enhance decision-making at local to global scales. TRMM and GPM precipitation observations can be quickly and easily accessed via various data portals. This PowerPoint provides examples of how GPM is being applied routinely and operationally across a range of societal benefit areas. 2 Societal Benefit Areas Extreme Events and Disasters • Landslides • Floods • Tropical cyclones • Re-insurance Water Resources and Agriculture • Famine Early Warning System • Drought • Water Resource management • Agriculture Weather, Climate & Land Surface Modeling • Numerical Weather Prediction • Land System Modeling • Global Climate Modeling Public Health and Ecology • Disease tracking • Animal migration • Food Security 3 Numerical Weather PreDiction • Air Force Weather Agency (AFWA) (557th Weather Wing) incorporates GMI data into their Weather Research and Forecasting (WRF) Model, delivering operational worldwide weather products to Air Force and Army units, unified commands, National Programs, and the National Command Authorities. • Joint Center for Satellite Data Assimilation (JCSDA/NOAA): brings GMI data into their Global Data Assimilation System (GDAS), which is used by the Global Forecast System (GFS) model to initialize weather forecasts with observational data. • Naval Research Lab (NRL): Uses GMI and other sensors in their Automated Tropical Cyclone Forecasting System (ATCF) for improved track prediction. • European Centre for Medium-Range Weather Forecasts (ECMWF): uses GPM data operationally within their global numerical weather prediction model focusing on medium range (up to two weeks ahead) forecasts. 4 4 GPM Data useD for Operational Tropical Cyclone Tracking The Naval Research Lab (NRL) routinely uses GPM Microwave Imager (GMI) data along with other sensors in their Automated Tropical Cyclone Forecasting System for improved storm track prediction. The NRL’s forecasts are used by weather prediction and disaster response organizations around the world.

The official “best” track is shown by the black line with hurricane symbols. Each point represents the forecast location at 24- hour intervals starting with the analysis time and ending with the forecast hour valid at the last best-track data point. Kevin Garrett/JCSDA 8 South Carolina Storms, October 2015 NASA’s Land Information System routinely assimilates GPM data as a forcing input for their regional and global instances. The example shows heavy rainfall from IMERG (left) and extreme “relative” soil moisture maximums in the areas of heavy rain for a major South Carolina rainfall event in October, 2015. Forecasters are provided this data in near real- time by SPoRT at MSFC and the data are actively being assessed with feedback provided by partners in Raleigh, among other Eastern Region NWS forecast offices. In the top right image, dark blues and purples suggest that these soils are holding 70-95+% of their water capacity, hence significant and immediate runoff that contributes to flash flooding. Both GPM and modeled products like soil moisture are also being used during disasters by FEMA and other response agencies to improve situational awareness. 9 GPM used for Flood Estimation for Oroville Dam, February 2017 IMERG Rainfall (7-day accum.) 21 Feb 2017 GPM IMERG precipitation is used by the Global Flood Monitoring System (GFMS) to detect potential flooding conditions and estimate intensity. This system also uses GEOS- X Oroville 5 forecast to estimate streamflow within affected areas. Top left shows the 7-day IMERG rainfall totals over California ending on 21 Feb. 2017. Top middle plot shows forecasted 3- day rainfall from the GEOS-5 model near the Oroville Dam area.

Analysis of the TRMM seasonal rainfall compared to previous years on record suggested that the 45 days leading up to the event ranked 3rd highest on record since 2000. GPM data is vital for improving this long record to evaluate seasonal variability of landslide triggering. 12 Global Landslide Nowcasting for California, February 2017 A global landslide nowcast model provides situational awareness of landslide hazards for a wide range of users. The model uses IMERG near real-time data with a global susceptibility map to identify locations with landslide potential. 1-day IMERG rainfall accum Landslide Nowcast for Feb 21st, 2017 Feb 21st, 2017 Alameda County, CA Landslide 2/20/2017 Credit: Alameda County 1-day IMERG rainfall accumulation (left) for the U.S. West Coast and corresponding landslide nowcasts (right) are shown for Feb. 21st, 2017 results are updated every 30 minutes. NASA landslide susceptibility, hazard, and rainfall data are available globally in near real-time and have been used by many international and domestic organizations, such as the World Bank, World Food Programme, Pacific Disaster Center, FEMA, and the US Army Corps of Engineers. 13 Kirschbaum/Stanley https://pmm.nasa.gov/precip-apps Global Fire Weather Data and Forecasting The Fire Weather Index System is the most widely used fire danger rating system in the world. The Global Fire WEather Database (GFWED) developed at NASA GISS integrates different weather factors influencing the likelihood of a vegetation fire starting and spreading. Calculations require measurements of temperature, relative humidity, wind speed, daily snow-depth, and precipitation totaled over the previous 24 hours. GPM IMERG data, as well as GPCP, TRMM, MERRA-2 and GEOS-5 are incorporated in different versions of the GFWED and are used by fire management agencies around the world. Aqua/Terra MODIS Active Fires

Interactive comment on “Comparison of AOD between CALIPSO and MODIS: significant differences over major dust and biomass burning regions” by X. Ma et al. Anonymous Referee #1 Received and published: 24 December 2012 Comments to the Editor: In this paper, author compares the aerosol optical depth (AOD) retrieved by two sen- sors namely, CALIPSO/CALIOP and Terra-Aqua/MODIS, over major dust and biomass burning regions of the world. Author uses level-3 gridded dataset available from both sensors to perform the analysis. They find that though the spatial patterns in AOT appear similar CALIOP tends to retrieve much lower AOD over the Sahara and north- west China; both are source regions of dust outbreaks. On the other hand, CALIOP is found to be higher-than-MODIS in the retrieved AOD over southern African region C3425 where seasonal biomass burning takes place. However, during burning season over South America, CALIOP tends to be lower-than-MODIS which apparently linked to the aerosol load/AOD. Finally, author attributes the discrepancies observed between two sensors to the algorithmic issues such as lidar ratio in CALIOP inversion and aerosol model and surface reflectance in MODIS algorithm. Though author calls for further research to narrow down the exact source of bias, he/she doesn’t show in this paper which sensor is closer to the ground-truth. My main suggestion to author is that he/she should compare both satellite retrievals with AERONET-measured direct AOD values in order to establish the validity of the two products.

In presenting this thesis in partial fulfillment of the Bachelor’s Degree from the Department of Geology and Geophysics, Yale University, I agree that the department may make copies or post it on the departmental website so that others may better understand the undergraduate research of the department. I further agree that extensive copying of this thesis is allowable only for scholarly purposes. It is understood, however, that any copying or publication of this thesis for commercial purposes or financial gain is not allowed without my written consent. Ariege Besson, 02 May 2018 Abstract GRACE is a pair of satellites that fly 220 kilometers apart in a near-polar orbit, mapping Earth’s gravity field by accurately measuring changes in distance between the two satellites. With a 15 year continuous data record and improving data processing techniques, measurements from GRACE has contributed to many scientific findings in the fields of hydrology and geology. Several of the applications of GRACE data include mapping groundwater storage changes, ice mass changes, sea level rise, isostatic rebound from glaciers, and crustal deformation. Many applications of GRACE data have profound implications for society; some further our understanding of climate change and its effects on the water cycle, others are furthering our understanding of earthquake mechanisms.

Acquiring high-precision and high-resolution precip- itation data in a large area is still a great challenge. In this study, a downscaling–merging scheme based on random forest and cokriging is presented to solve this problem. First, the enhanced decision tree model, which is based on random forest from machine learning algorithms, is used to reduce the spatial resolution of satellite daily precipitation data to 0.01◦. The downscaled satellite-based daily precipitation is then merged with gauge observations using the cokriging method. The scheme is applied to downscale the Global Precipitation Measurement Mission (GPM) daily precipitation product over the upstream part of the Hanjiang Basin. The experimental results indicate that (1) the downscaling model based on random forest can correctly spatially downscale the GPM daily Citation: Yan, X.; Chen, H.; Tian, B.; precipitation data, which retains the accuracy of the original GPM data and greatly improves their Sheng, S.; Wang, J.; Kim, J.-S.
