We have successfully completed the Costa Rica deployment where we observed the tropical forest biome in La Selva on February 18, 21, and 24 respectively.  Science team members were in the field on the last two flights making soil moisture measurements and collecting vegetation information and other ancillary data.  We also had the opportunity to acquire P-band radar data in experimental modes during the last two flights, the 60 MHz bandwidth mode (instead of the typical 20 MHz mode) and the split bandwidth mode where we alternately transmitted 80 MHz bandwidth chirps centered at 400 MHz and 320 MHz respectively.  These modes were only tested in the lab and have never been used by AirMOSS in the United States before due to the 420-440 MHz frequency license restriction we have in the US.  We were able to generate quick look imagery to verify that the experimental modes worked successfully (see attached images with low and high sideband data).  The split band mode will allow us to investigate differential foliage/ground penetration at slightly different frequencies.
