Eric Webster, vice president of Exelis Weather Systems, talked recently about the company’s efforts along with NASA Langley Research Center to evaluate an Exelis instrument to determine its effectiveness for measuring CO2 from space.

NOAA researchers have a new instrument unofficially named “Seahorse” that is used on the ocean floor to study sea scallops. Named Seahorse because it is spiny and curved, the instrument is a sophisticated, up-to-date version of a survey system developed at the Woods Hole Oceanographic Institution (WHOI) and used on sea scallop resource surveys conducted by NOAA’s Northeast Fisheries Science Center (NEFSC).
High resolution imagery of sub-meter – less than 40 inches – is only available from GeoEye, DigitalGlobe, Astrium Geo, and ImageSat. It is what the stuff of Google is made of. GeoEye and DigitalGlobe represent approximately 75% of this market, and 2/3 of their revenue is tied to the U.S. government. There are lots of free, government sources of satellite imagery like Landsat, and weather satellites from NASA and NOAA, but these are not high-resolution satellites that can zoom in on your house, or support 3D modeling for engineering and virtual reality-type applications.
Read about why U.S. commercial satellite imagery is important:
The National Oceanic and Atmospheric Administration’s (NOAA) Center for Climate Prediction holds a monthly drought briefing by teleconference to identify the latest drought areas in North America, according to Don Comis of the USDA Agricultural Research Service (ARS). ARS scientists, Martha Anderson and Bill Kustas, are hoping that in a year or so, data from their computer model/satellite package will give evapotranspiration (ET) maps a seat at that briefing.
This morning, the National Weather Service’s Space Weather Prediction Center based in Boulder, Colorado, published a map showing a solar radiation storm touching the upper atmosphere in the Earth’s poles. According to their report the Earth is being bombarded with the strongest blast of radiation from the sun since 2003. This event could cause problems for communications and air travel.

Wintertime droughts are increasingly common in the Mediterranean region, and human-caused climate change is partly responsible, according to a new analysis by NOAA scientists and colleagues at the Cooperative Institute for Research in Environmental Sciences (CIRES). In the last 20 years, 10 of the driest 12 winters have taken place in the lands surrounding the Mediterranean Sea.
Here is a collection of resources for GIS data on American Samoa, the area hit by tsunami last week. GISCorps’ Shoreh Elhami said that as of yet, they have not received any requests for volunteers.
