S5P_L2__CLOUD__HiR: Sentinel-5P TROPOMI Cloud Measurements

From August 6, 2019 onward, this dataset provides Level-2 cloud products from the Sentinel-5P satellite's TROPOMI instrument. It contains cloud properties retrieved by two algorithms: OCRA for fractional cloud cover and ROCINN for cloud optical thickness and cloud top height. The data offers high spatial resolution (~5.5 km at nadir) and covers ultraviolet-visible, near infrared, and shortwave infrared wavelengths.

Use Cases

• Monitoring fractional cloud cover globally using the OCRA algorithm.
• Analyzing cloud optical thickness and cloud top height via the ROCINN neural network algorithm.
• Studying cloud reflectance and radiative transfer for climate research.
• Validating atmospheric models with high-resolution satellite cloud observations.

Strengths

• High spatial resolution (~5.5 km at nadir) implemented from August 6, 2019.
• Cloud properties derived from two distinct algorithms (OCRA and ROCINN) for complementary measurements.
• Data is part of the Copernicus Sentinel mission, a joint initiative between ESA and the Netherlands.

Limitations

• Column names and exact data structure are not provided in the metadata.
• Dataset size, row count, and specific license details are unknown or unspecified.
• Data availability is split across three collections based on processor version and date, requiring users to select the correct one.
