We develop the Tropospheric Emission Spectrometer (TES) carbonyl sulfite (OCS) retrieval algorithm and present the initial oceanic results showing the seasonal and latitudinal distribution of carbonyl sulfite in the free troposphere. The analysis using the developed retrieval strategy show that TES: (1) generally provides less than 1.0 degree of freedom for signal (DOFS), (2) is sensitive in the mid troposphere with peak sensitivity typically between 300 to 500 hPa, (3) error analysis suggests a large amount of average is required to remove the random error from the useful information of the variability in the OCS. (4) With data averaging, TES OCS retrievals are consistent (within the calculated uncertainties) of ground and aircraft based measurements and are able to capture the seasonal variation and latitudinal gradient over Pacific region.
