Laying the Groundwork - First Photos from the Field!
GPM's ground validation scientist, Walt Petersen sent us our first photos from the CARE site in Ontario, Canada. Snow's already on the ground, now we're just waiting for more to fall! The University of Bonn ADMIRARI Radiometer deployed at the CARE site. It measures microwaves that are naturally emitted from Earth's surface to determine water vapor and cloud and liquid water in the air column.

This radar scans the air column for snow falling from the
clouds to the ground. It uses two frequencies that together can determine
the shape and size of snowflakes, and the distribution of those sizes
throughout the clouds and snowing area.
