Upper Brahmaputra River Basin Precipitation at 5 km and 3-Hour Resolution (1981-2016)

36 years of precipitation data from 1981 to 2016 for the Upper Brahmaputra River Basin, with a 3-hour temporal resolution and 5 km spatial resolution. The dataset integrates five reanalysis and satellite products with ground observations from 9 CMA meteorological stations and 166 MWR rain gauges. Yuanwei Wang from the Chinese Academy of Sciences created this dataset to support hydrological and climate studies.

Use Cases

• Modeling hydrological process responses to climate change based on the integrated precipitation products.
• Analyzing high temporal resolution precipitation patterns using the 3-hourly data.
• Validating satellite and reanalysis precipitation estimates against the 175 ground observation stations.
• Studying spatial precipitation distribution at a 5 km resolution across the river basin.

Strengths

• Integrates data from five distinct reanalysis and satellite sources with 175 ground-based observation points.
• Provides high-resolution data with a 3-hour time step and 5 km spatial grid over a 36-year period (1981-2016).
• Data is formatted with ArcGIS-compatible header files for direct geospatial analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Data format is TXT files requiring specific parsing logic for the 292x79 grid and variable monthly row counts.
