Abstract
A summer 2021 European airborne field campaign-the Land surface Interactions with the Atmosphere over the Iberian Semi-arid Environment (LIAISE) campaign-presented an opportunity to explore passive soil moisture sensing with footprints as small as 100x200m, contributing a key measurement to LIAISE and providing a rare opportunity to gain detailed insight into the water/energy/carbon exchanges at such plot-scale resolution over a $17 \mathrm{x}5$ km area. NASA Goddard's Scanning L-band Active Passive (SLAP) sensor-an airborne simulator of the Soil Moisture Active Passive (SMAP) satellite-made nine soil moisture flights near Lleida, Spain during 15–29 July. We present soil moisture imagery and histograms spanning irrigated and non-irrigated land and their response to a precipitation event followed by a drydown.
