MOPITT ATBD Conversion of MOPITT Digital Counts into Calibrated Radiances in Carbon Monoxide and Methane Absorption Bands (Level 0 - 1)
Entry ID: 02-mopitt-99
Abstract: (Summary adapted from the MOPITT ATBD Level 1-B pdf file)
This document briefly outlines the Measurement of Pollution in the
Troposphere (MOPITT) investigation and describes the physics and
mathematics of the algorithms that convert the instrument outputs from
raw digital counts (Level-0 data) into geolocated, calibrated
radiances which make up the Level-1 data product (MOP-01).
The Level 1 ... outputs from these algorithms will subsequently be used as
inputs to the algorithms that retrieve vertical profiles of carbon
monoxide, and total column amounts of carbon monoxide and methane
(Level 2 data). The algorithms that create the Level 2 data from the
Level 1 data are discussed in a separate ATBD.
The global distribution of these profiles and column amounts will be
used in descriptive studies of methane and carbon monoxide
gases. MOPITT will thus provide the first detailed, long-term, global
information on the CH 4 and CO horizontal, vertical and temporal
variations, their relationships to other activities such as: biomass
burning, industrial activity, thunderstorm venting of the boundary
layer, etc. They will also be used in parallel modeling efforts to
advance our understanding of global tropospheric chemistry and its
relationship to sources, sinks, and atmospheric transports, which can
be determined from other data.
