S5P_L2__CO_____HiR_NRT: Near-Real-Time Global Carbon Monoxide Columns

Sentinel-5P satellite data provides global carbon monoxide total column measurements within three hours of observation, intended for rapid environmental assessment. The TROPOMI instrument uses a modified SWIR retrieval algorithm (SICOR) operating between 2305nm and 2385nm to measure CO under various atmospheric conditions. Each data granule contains one orbit of information at a spatial resolution of 5.5km x 7km and is stored in ~20 MB netCDF4 files.

Use Cases

• Monitoring wildfire and industrial pollution plumes based on near-real-time CO column data.
• Assessing atmospheric transport models using high spatial resolution (5.5km x 7km) global measurements.
• Validating air quality forecasts with data available within three hours of satellite overpass.
• Studying carbon monoxide sources and sinks under cloudy conditions using the SICOR algorithm.

Strengths

• Data is available in near-real-time, typically within three hours of measurement.
• Provides global coverage at a high spatial resolution of 5.5km x 7km.
• Uses an algorithm (SICOR) designed to account for cloudy and aerosol-loaded atmospheric conditions.

Limitations

• Data is only archived for up to ten days, limiting long-term analysis on this platform.
• Key metadata such as row count, column names, and specific license terms are not provided across sources.
• The 'last updated' date (2026-04-09) appears inconsistent as it is a future date.
