NASA Marshall Space Flight Center’s SERVIR and Short-term Prediction Research and Transition (SPoRT) Center programs have been selected to host Komlan “Richard” Folly, a native of Togo, West Africa, participating in the prestigious Mandela Washington Fellowship for Young African Leaders in August and September 2017. The Mandela Washington Fellowship, the flagship program of the Young African Leaders Initiative (YALI), empowers young African leaders through academic coursework, leadership training, and networking opportunities. The Fellows, who are between the ages of 25 and 35, have established records of accomplishment in promoting innovation and positive change in their organizations, institutions, communities, and countries. These young leaders represent the diversity of Africa, including equal numbers of women and men, individuals with disabilities, and people from both urban and rural areas.

The RCMRD Space Challenge 2017 Awards Ceremony was held on July 7, 2017, at the Regional Centre for Mapping of Resources for Development (RCMRD) in Nairobi, Kenya. Seven schools participated in the challenge, which was split into three parts: orientation for teachers, installation of automatic weather stations in select schools, and recording of data on three parameters. This RCMRD Space Challenge program will endeavor to showcase to the primary and secondary schools participating in the challenge the importance of data collection as well as the need for analysis and interpretation of the data collected in decision making. The Space Challenge is part of RCMRD’s strategy to engage young people within its member States.

The SERVIR-Amazonia Request for Application (RFA) has been extended to 13 October 2017. As described in the grant opportunity posted at grants.gov: The SERVIR Amazonia activity will support a regionally focused consortium to pursue the following objectives: (1) Strengthen a regional system or hub for dissemination of, and collaboration around, key publicly available precipitation and hydrologic monitoring and modeling data; (2) Build and institutionalize Amazon region capacity for generation, dissemination, and use of geospatial information and tools for decision support; and (3) Develop user-tailored tools to inform government and civil society decision making.

Sentinel-1 radar map for September 2017 Raboso-Puebla Earthquake in Mexico indicates relatively small permanent ground motions
NASA and its partners are contributing important observations and expertise to the ongoing response to the September 19, 2017, magnitude 7.1 Puebla earthquake in Mexico. This earthquake has caused widespread building damage and triggered landslides throughout the region, including Mexico City. Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA's Jet Propulsion Laboratory, Pasadena, California, and the California Institute of Technology in Pasadena, analyzed interferometric synthetic aperture radar images from the radar instrument on the Copernicus Sentinel-1A and Sentinel-1B satellites, operated by the European Space Agency (ESA), to calculate a map of the deformation of Earth's surface caused by the quake. This false-color map shows the amount of permanent surface movement caused almost entirely by the earthquake, as viewed by the satellite, during a 12-day interval between radar images acquired by the two Sentinel-1 satellites on September 8 and September 20, 2017. This preliminary map came from automatic processing by the ARIA system.

Mexico City Damage Proxy Map
NASA’s ARIA Damage Proxy Map of the M7.1 Raboso, Mexico, earthquake was created from the Copernicus Sentinel-1 satellite SAR data and is available to download from: http://aria-share.jpl.nasa.gov/events/20170919-M7.1_Raboso_Mexico_EQ/DPM The Advanced Rapid Imaging and Analysis (ARIA) team at NASA's Jet Propulsion Laboratory in Pasadena, California, and Caltech, also in Pasadena, created this Damage Proxy Map (DPM) depicting areas of Central Mexico, including Mexico City, that are likely damaged (shown by red and yellow pixels) from the magnitude 7.1 Raboso earthquake of Sept. 19, 2017 (local time). The map is derived from synthetic aperture radar (SAR) images from the Copernicus Sentinel-1A and Sentinel-1B satellites, operated by the European Space Agency (ESA). The images were taken before (Sept. 8, 2017) and after (Sept. 20, 2017) the earthquake. The map covers an area of 109 by 106 miles (175 by 170 kilometers). Each pixel measures about 33 yards (30 meters) across. The color variation from yellow to red indicates increasingly more significant ground surface change. Preliminary validation was done by comparing the DPM to a crowd-sourced Google Map (https://www.google.com/maps/d/u/0/viewer?mid=1_-V97lbdgLFHpx-CtqhLWlJAnY...). This damage proxy map should be used as guidance to identify damaged areas, and may be less reliable over vegetated areas. Sentinel-1 data were accessed through the Copernicus Open Access Hub. The image contains modified Copernicus Sentinel data (2017), processed by ESA and analyzed by the NASA-JPL/Caltech ARIA team. This research was carried out at JPL under contract with NASA.

IMERG precipitation accumulation from Hurricane Maria 9/17/17 - 9/21/17
Hurricane Maria has caused catastrophic flooding in Puerto Rico. Extreme flooding was reported in the streets of San Juan, the capital of Puerto Rico. The National Weather Service issued flash flood warnings for the entire island. Hurricane Maria has now moved to the northwest of Puerto Rico but is still expected to contribute to rainfall over the island on Friday. Feeder bands are transporting rain over Puerto Rico and the Dominican Republic even as the hurricane moves toward the Turks and Caicos islands. NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) data were used to estimate the total amount of rain that Hurricane Maria dropped from September 17 to early September 21, 2017. During that period Maria dropped heavy rain in the Leeward Islands, Virgin Islands and Puerto Rico. IMERG estimated that rainfall totals greater than 10 inches (254 mm) were common along Maria's track. IMERG rainfall estimates indicated that more than 20 inches (512 mm) of rain fell over a large part of Puerto Rico. Video of NASA Measures Hurricane Maria's Track of Torrential Rainfall

GPM overpass of hurricane Maria from 9/18/17
Intensifying hurricane Marie is on a path that is predicted to impact the Leeward Islands. Hurricane Irma caused death and wide spread destruction there less than two weeks ago. Very powerful convective storms and multiple lightning strokes within Maria have been cited as proof that Maria is an energetic intensifying hurricane. The GPM core observatory satellite had an excellent view of hurricane Maria when it passed almost directly above the hurricane on September 17, 2017 at 1001 PM AST (September 18, 2017 0201 UTC). GPM's Microwave Imager (GMI) and Dual-Frequency Precipitation Radar (DPR) showed that Maria had well defined bands of precipitation rotating around the eye of the tropical cyclone. GPM's radar (DPR Ku band) found rain falling at a rate of over 6.44 inches (163.7 mm) per hour in one of these extremely powerful storms northeast of Maria's eye. A 3-D view of Maria's precipitation structure was accomplished using data from GPM's Radar (DPR Ku band). Intense thunderstorms were found towering to above 9.7 miles (15.7 km). This kind of chimney cloud, also called a "hot tower" (as it releases a huge quantity of latent heat by condensation). These tall thunderstorms in the eye wall are often a sign that a tropical cyclone is becoming more powerful.
