CLAMPS2 TROPoe Thermodynamic Retrievals

These files contain 24 hour periods of retrieved thermodynamic profiles derived from observations collected by the CLAMPS2 atmospheric emitted radiance interferometer (AERI). The TROPoe algorithm is a python equivalent to the AERIoe algorithm (see Turner and Loehnert, 2014; Turner and Blumberg 2019). These data were collected during the SCALES project. AERI only data is available. The CLAMPS2 platform includes an ABB-AERI and RPG HATPRO MWR. The AERI consists of a Fourier transform interferometer, scene scanning-optics, IR detector, calibration blackbodies, and instrument control hardware. The exact system design and extensive theory of operation can be found in Knuteson et al. (2004). On a clear sky day it is capable of measuring IR radiances throughout the depth of the atmosphere with a wavenumber resolution 1 cm-1 and temporal resolution of ~20 seconds. The AERI has an absolute accuracy of < 1% of the ambient blackbody radiance and has typical noise < 0.2 mW (m2 sr cm-1)-1. The instrument is not able to collect observations in precipitation and when precipitation is detected a mechanical hatch is closed to protect the instrument. The radiances collected by the AERI contain information that can be used to obtain profiles of temperature, water vapor and trace gases as well as basic cloud properties. A MWR is a microwave receiver that measure the emission of microwave radiation from the atmosphere. The RPG HATPRO MWR observes microwave brightness temperatures in seven channels in the 22-31 GHz band and seven channels in the 51-58 GHz band. Information on the water vapor and integrated quantities of liquid water is in the 22-31 GHz band and temperature profile information is in the 51-58 GHz band.
