The Status of Quality Measurement Experiments in the Microwave, Longwave, and Shortwave

Spectral analyses from the Atmospheric Emitted Radiance Interferometer/Line-by-Line Radiative Transfer Model (AERI/LBLRTM) Quality Measurement Experiment (QME) have proven critical in the assessment of clear sky radiative transfer modeling capability for general circulation models (GCMs). The QME provides a mechanism for the assessment of the three critical components of the longwave spectral validation: 1) the high resolution spectral radiance measurements from the University of Wisconsin AERI The longwave AERI/LBLRTM QME has made important instrument, 2) the line-by-line calculation from the LBLRTM contributions to the detection and evaluation of data quality algorithm, and 3) the characterization of the atmospheric state problems related to the continuous long-term measurements at in the radiating column as derived from various instruments at the ARM SGP site.
