SMAP

I’ve worked on SMAP since before launch in 2015, starting in graduate school. I lead development of the mission’s L-band freeze–thaw algorithm — from the original detection method, first validated on Aquarius, to the operational Level-3 Freeze/Thaw data record NASA distributes today. I’m first author on that data product and on the JSTARS paper introducing the Aquarius-based detection method it grew out of.

I’m now carrying that L-band expertise into the next era: as PI of a five-year NASA ROSES award, I lead development of the joint SMAP–NISAR active-passive soil-moisture algorithm — the retrieval method the mission will use once NISAR L-band SAR data is available to fuse with SMAP’s radiometer measurements.
