Sentinel-5P TROPOMI Near-Real-Time (NRT) Carbon Monoxide CO Column 1-Orbit L2 5.5km x 7km V2 (S5P_L2__CO_____HiR_NRT) at GES DISC

Description

The Sentinel-5P TROPOMI Near Real Time (NRT) Carbon Monoxide CO Column 1-Orbit L2 5.5km x 7km V2 (S5P_L2__CO_____HiR_NRT) at GES DISC is the near real time version of the offline S5P_L2__CO_____HiR data product. These data are typically available within three hours of measurement as required by the Land Atmosphere NRT Capability Earth Observing System (LANCE). These data are intended for a rapid turnaround assessment and are only archived for up to ten days. Users who require a longer data record, or wish to conduct rigorous analysis should use the offline version of this product S5P_L2__CO_____HiR. The Copernicus Sentinel-5 Precursor (Sentinel-5P or S5P) satellite mission is one of the European Space Agency's (ESA) new mission family - Sentinels, and it is a joint initiative between the Kingdom of the Netherlands and the ESA. The sole payload on Sentinel-5P is the TROPOspheric Monitoring Instrument (TROPOMI), which is a nadir-viewing 108 degree Field-of-View push-broom grating hyperspectral spectrometer, covering the wavelength of ultraviolet-visible (UV-VIS, 270nm to 495nm), near infrared (NIR, 675nm to 775nm), and shortwave infrared (SWIR, 2305nm-2385nm). Sentinel-5P is the first of the Atmospheric Composition Sentinels and is expected to provide measurements of ozone, NO2, SO2, CH4, CO, formaldehyde, aerosols and cloud at high spatial, temporal and spectral resolutions. The TROPOMI Carbon Monoxide total column applies a modified SWIR CO retrieval (SICOR) algorithm based on the CO absorption band between 2305 nm and 2385 nm. The S5P SICOR algorithm accounts for cloudy and aerosol loaded atmosphere conditions and is suitable for clear sky observations over land and cloudy observations over both land and oceans. Data are stored in individual files, or granules, that contain one orbit of information. The data are stored in netCDF4 data format and files and complete files are ~20 MB.
