Abstract

This dataset contains the Total Column Carbon Monoxide (CO) data produced within the Earth Observation Climate Information Service (EOCIS) project. The CO_ULIRS product is derived from measurements made by the Infrared Atmospheric Sounding Interferometer (IASI) onboard the MetOp satellite series. CO_ULIRS uses an optimal estimation approach to derive carbon monoxide total column amounts from IASI spectra using the University of Leicester IASI Retrieval Scheme (ULIRS).

Instrument/Platform pairings

IASI Deployed on: Metop-B

Computation Element: 1

Title University of Leicester IASI retrieval scheme (ULIRS)
Abstract This computation involved: ULIRS deployed on JASMIN processing cluster. The ULIRS is an optimal estimation-based retrieval scheme, which utilises equidistant pressure levels and a floating pressure grid based on topography. ULIRS was developed at the University of Leicester through the National Centre for Earth Observation (NCEO).
