TES L1B Subsystem is a computer program that performs several functions for the Tropospheric Emission Spectrometer (TES). The term "L1B" (an abbreviation of "level 1B"), refers to data, specific to the TES, on radiometric calibrated spectral radiances and their corresponding noise equivalent spectral radiances (NESRs), plus ancillary geolocation, quality, and engineering data. The functions performed by TES L1B Subsystem include shear analysis, monitoring of signal levels, detection of ice build-up, and phase correction and radiometric and spectral calibration of TES target data. Also, the program computes NESRs for target spectra, writes scientific TES level-1B data to hierarchical- data-format (HDF) files for public distribution, computes brightness temperatures, and quantifies interpixel signal variability for the purpose of firstorder cloud and heterogeneous land screening by the level-2 software summarized in the immediately following article. This program uses an in-housedeveloped algorithm, called "NUSRT," to correct instrument line-shape factors.
This program was written by Richard C. De Baca, Edwin Sarkissian, Mariyetta Madatyan, Douglas Shepard, Scott Gluck, Mark Apolinski, James McDuffie, and Dennis Tremblay of Caltech for NASA's Jet Propulsion Laboratory.
