S5P_L1B_RA_BD4_HiR_NRT: Near-Real-Time Satellite Radiance Data

Sentinel-5P satellite data provides near-real-time ultraviolet-visible (UV-VIS) radiance measurements from the TROPOMI instrument. These Level-1B data granules, each covering one orbit and stored in netCDF4 format, are intended for rapid assessment and are typically available within three hours of measurement. The data are archived for only up to ten days, with users requiring longer records advised to use the offline product version.

Use Cases

• Rapid assessment of atmospheric radiation based on near-real-time availability within three hours.
• Monitoring ultraviolet radiance levels based on UV-VIS detector band 4 data.
• Calibration and validation of atmospheric models based on provided radiance and irradiance products.
• Short-term analysis of orbital atmospheric data based on individual granule files containing one orbit of information.

Strengths

• Data availability is rapid, typically within three hours of measurement.
• Individual data files are complete and substantial, each being 0.650 GB.
• The dataset is part of a major joint satellite mission between ESA and the Kingdom of the Netherlands.

Limitations

• The data record is short-term, archived for only up to ten days.
• Column names and detailed schema are unknown across all platform descriptions.
• Metadata for size, row count, and specific license details are conflicting or unspecified across sources.
