Net Radiation and Albedo Time Series for Xingu River Basin

Upper Xingu River Basin in Mato Grosso, Brazil, is covered by this 8-day time series of daily average land surface net radiation (Rnet) and its component parameters at approximately 0.5 km resolution. Data spans from February 2000 to November 2012, derived from MODIS satellite products and local weather station data under all sky conditions. The dataset is provided by ORNL_CLOUD.

Use Cases

• Modeling land surface energy balance using derived parameters like albedo, downward shortwave radiation (RSnet), and upward/downward longwave radiation (RLnet[up], RLnet[down]).
• Analyzing long-term trends in net radiation (Rnet) to assess climate impacts of land cover change in the Amazon basin.
• Calibrating regional climate models with MODIS-based radiation estimates fused with local weather station observations.
• Studying the radiative effects of deforestation and agricultural expansion in a major Amazon tributary basin.

Strengths

• Provides a 12.7-year continuous time series from 2000-02-18 to 2012-11-16.
• Integrates multiple MODIS products (MOD43A3, MOD11A2, MOD08E3) with local weather station data for parameter estimation.
• Offers data at a relatively high spatial resolution of approximately 0.5 km for the basin.

Limitations

• Key metadata such as row count, column names, and exact file size are unknown across all sources.
• There is a conflict in the 'last updated' date: one source states 2012-11-16, while others state 2026-03-12, suggesting possible metadata errors.
