The L-band radar aboard the JSC G-III is in the midst of the SnowEx campaign, where we have been imaging a dozen instrumented sites in Western U.S. to study the utility of repeat-pass L-band InSAR for monitoring snow water equivalent in several snow climates in California, Idaho, Utah, Colorado, and New Mexico.  We will conduct weekly observations whenever possible through the end of March, then bi-weekly observations through early May.
