Abstract. The Generalized Aerosol Retrieval from Radiometer and Lidar Combined data algorithm (GARRLiC) the LIdar-Radiometer Inversion Code (LIRIC) provide opportunity to study aerosol vertical distribution by combining ground-based lidar sun-photometric measurements.

Atmospheric emissions of reactive nitrogen in the form dioxide (NO2) and ammonia (NH3) worsen air quality upon deposition, dramatically affect environment. Recent infrared satellite measurements have revealed that NH3 emitted by industries are an important underestimated emission source. Yet, to assess these emissions, current sounders severely limited their spatial resolution.

Abstract. Over the past decade, hyperspectral infrared sounders on satellites have offered global measurements of atmospheric ammonia (NH3), providing valuable insights into its sources. However, due to their coarse spatial resolution and gaps in coverage, inferring emissions from smaller sources or utilizing data single overpasses remains very challenging. While a high imaging-sounder would greatly enhance monitoring capabilities, developing an instrument that combines spectral is...
