NASA's TRMM Satellite sees most of Ida's heaviest rain stayed off coasts
NASA and the Japanese Space Agency's Tropical Rainfall Measuring Mission (TRMM) satellite flew over Ida and captured her rainfall when she passed by Nicaragua, Honduras and Belize this weekend. TRMM data revealed that most of the heaviest rainfall totals, as much as 11 inches, were just off the coasts of those countries, even though all of those areas dealt with flooding rains.
On November 6, 2009 at 1147 UTC (7:47 a.m. ET) TRMM revealed Ida had weakened to a tropical depression after coming ashore in eastern Nicaragua on November 5. TRMM identified the location of Ida's center of circulation and noted that much of the very heavy rainfall that occurred earlier had tapered off except for a few intense thunderstorms off the northeastern Honduras coast.
The National Hurricane Center in Miami, Florida predicted that Ida would blossom again into a tropical storm after moving into the Caribbean Sea off the coast of Honduras. Ida did enter Gulf of Mexico as a tropical storm, strengthened to a Category One Hurricane on the Saffir-Simpson Scale, and as of 10 a.m. ET on Monday, November 9, Ida had weakened to a Tropical Storm.
Ida's maximum sustained winds as of 10 a.m. ET on November 9 are now near 70 mph. Her center was located near 26.5N and 88.3W, and was moving north-northwest near 17 mph. Minimum central pressure is estimated near 996 millibars.
TRMM can be used to calibrate rainfall estimates from other satellites. The TRMM-based Multi-satellite Precipitation Analysis (TMPA) at the NASA Goddard Space Flight Center in Greenbelt, Md. monitors rainfall over the global Tropics. The TMPA rainfall analysis above shows that Ida produced heavy rainfall over large areas of eastern Nicaragua and Honduras. The highest rainfall totals of over 275 mm (~11 inches) were along the eastern Nicaragua coast as hurricane Ida came ashore.
Heavy rain amounts (from satellites) and flood potential calculations (from a hydrological model) are updated every three hours globally with the results shown on the "Global Flood and Landslide Monitoring" TRMM web site pages at http://trmm.gsfc.nasa.gov.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
