Soil NOx estimates from our field campaign compared to the average VSM and maximum temperature during the measurement period. Maximum temperature was determined for the sampling period from the CARB meteorology station at Calipatria and Thermal. VSM was determined for the Imperial Valley for Calipatria measurements and the Coachella Valley for Thermal measurements using SMAP satellite data, filtered for 4:30 pm (closest time to when Tmax occurs).
