S5P_L1B_RA_BD7_HiR_NRT: Near-Real-Time SWIR Radiance from Sentinel-5P

Near-real-time data from the Sentinel-5P satellite's TROPOMI instrument, typically available within three hours of measurement and archived for up to ten days. The Level-1B product provides calibrated radiance, irradiance, and engineering data from the shortwave infrared (SWIR, 2305nm-2385nm) band 7 detector at a spatial resolution of 5.5km x 21km. Data is stored in netCDF4 granules, with each file containing one orbit of information and being approximately 0.305 GB in size.

Use Cases

• Rapid assessment of atmospheric events based on near-real-time SWIR radiance measurements.
• Calibration and validation of atmospheric models using Level-1B radiance and irradiance products.
• Analysis of shortwave infrared spectral signatures for trace gas detection from the 2305nm-2385nm band.
• Operational monitoring of air quality and pollution plumes using data available within three hours.

Strengths

• Provides data within three hours of satellite measurement, supporting time-sensitive analysis.
• Data is processed by the authoritative KNMI TROPOMI L01B processor, ensuring a standard calibration chain.
• Each data granule contains a complete orbit of information, providing global coverage per file.

Limitations

• Data is only archived for up to ten days, limiting its use for long-term trend analysis.
• Column names and a detailed data schema are not provided in the available metadata.
• Sources show a version conflict (V3 vs. V2), indicating potential inconsistencies between platforms.
