Empirical Corrections to Instrument Artifacts in the MOPITT Data Stream;Technical note

摘要

Data is transmitted to Earth from the the Measurements Of Pollution In The Troposphere (MOPITT) instrument aboard NASA'a Terra satellite. The raw data (LO or LO) arrives at the National Center for Atmospheric Research (NCAR) in Boulder, CO. At NCAR, the LO data is conditioned in five ways to remove instrument artifacts: 1. Mirror Position Adjustment, 2. Time Monotonicity, 3. Sawtooth Irregularity, 4. Periodic Peak, 5. Packet Position Bias. Each of these artifacts are corrected either as pre-processing operations or while the LO data is being transformed into geolocated radiance measurements. This paper describes the corrections that occur which will assist any future engineer who wishes to reconstruct or improve the MOPITT data processing procedure.
