. Satellite measurements enable quantification of atmospherictemperature, humidity, wind fields, and trace gas vertical profiles. Themajority of current instruments operate on polar orbiting satellites andeither in the thermal and mid-wave or in the shortwave infrared spectralregions. We present a new multispectral instrument concept for improvedmeasurements from geostationary orbit (GEO) with sensitivity to the boundarylayer. The JPL GEO-IR Sounder, which is an imaging Fourier transformspectrometer, uses a wide spectral range (1–15.4 µm) encompassingboth reflected solar and thermal emission bands to improve sensitivity tothe lower troposphere and boundary layer. We perform retrieval simulationsfor both clean and polluted scenarios that also encompass differenttemperature and humidity profiles. The results illustrate the benefits ofcombining shortwave and thermal infrared measurements. In particular, theformer adds information in the boundary layer, while the latter helps toseparate near-surface and mid-tropospheric variability. The performance ofthe JPL GEO-IR Sounder is similar to or better than currently operationalinstruments. The proposed concept is expected to improve weatherforecasting as well as severe storm tracking and forecasting and also benefit localand global air quality and climate research.
