Daily Cropland Soil NO x Emissions Identified by TROPOMI and SMAP
We use TROPOMI (TROPOspheric Monitoring Instrument) tropospheric nitrogen dioxide (NO ) measurements to identify cropland soil nitrogen oxide (NO = NO + NO ) emissions at daily to seasonal scales in the U.S. Southern Mississippi River Valley. Evaluating 1.5 years of TROPOMI observations with a box...

description | We use TROPOMI (TROPOspheric Monitoring Instrument) tropospheric nitrogen dioxide (NO
) measurements to identify cropland soil nitrogen oxide (NO
= NO + NO
) emissions at daily to seasonal scales in the U.S. Southern Mississippi River Valley. Evaluating 1.5 years of TROPOMI observations with a box model, we observe seasonality in local NO
enhancements and estimate maximum cropland soil NO
emissions (15-34 ng N m
s
) early in growing season (May-June). We observe soil NO
pulsing in response to daily decreases in volumetric soil moisture (VSM) as measured by the Soil Moisture Active Passive (SMAP) satellite. Daily NO
enhancements reach up to 0.8 × 10
molecules cm
4-8 days after precipitation when VSM decreases to ~30%, reflecting emissions behavior distinct from previously defined soil NO
pulse events. This demonstrates that TROPOMI NO
observations, combined with observations of underlying process controls (e.g., soil moisture), can constrain soil NO
processes from space. |
