Description
TES/Aura L2 Carbonyl Sulfide Nadir V008 contains vertical profile estimates of carbonyl sulfide (OCS) retrieved from limb observations by the Tropospheric Emission Spectrometer aboard NASA's Aura satellite. The dataset includes retrieved profiles, associated error matrices, surface temperature, cloud optical depth, quality flags, averaging kernels, and a priori constraints. Data collection is complete, spanning from the satellite's launch on July 15, 2004, with global surveys covering up to 16 consecutive orbits.
Use Cases
Analyzing vertical profiles of carbonyl sulfide for atmospheric chemistry studies based on retrieved species profiles.
Assessing retrieval uncertainty for climate models using the provided error diagonals and covariance matrices.
Studying cloud interactions with trace gases using the included cloud effective optical depth estimates.
Validating satellite retrieval algorithms by comparing observed spectra to L2 modeled spectra.
Investigating global sulfur compound transport patterns from limb observation data collected over 16-orbit surveys.
Strengths
Includes detailed error characterization with diagonals and covariance matrices for profile estimates.
Provides ancillary data common to both nadir and limb files, enhancing cross-observation analysis.
Data collection spans a defined operational period from launch on July 15, 2004, to completion.
Observation methodology evolved, with global surveys increasing from two to three low-resolution scans after April 24, 2005.
Limitations
Specific column names and dataset size (rows, size) are not provided in any source.
Metadata completeness is low; license is listed as 'other-license-specified' without details, and author/organization are largely unknown.
