be the LaRC G-III, which does not have the range we would prefer, but does offer the capability of accommodating the most needed instruments – the HALO water vapor lidar and the AVIRIS imager, as well as dropsondes. The "low flier" will be the WFF P-3, with
a payload that combines remote sensing, in-situ, and radiation measurements of the atmosphere and the surface/cryosphere – more on the details in our kickoff telecon.</span></p>
