This week the JSC G-III-mounted AirMOSS radar is stationed at Ellington Field, TX while we conduct observations in Mexico and Oklahoma.  The Mexico flights are our third and last annual observation over Chamela’s subtropical dry forest.  The flights over Marena, OK, a SMAP calibration site over temperate grassland, is the first observation of the year.  Both the radar and the aircraft have been performing well and at the end of the week, we will wrap up the spring observations while the aircraft will be reconfigured for astronaut return mission.
