Breathing Earth System Simulator (BESS) Radiation v1

AI-generated Key Takeaways

• The BESS Radiation dataset provides daily estimates of shortwave radiation and photosynthetically active radiation (PAR) at a 5km resolution.

• It covers the period from 2001 to 2021 and is derived from MODIS atmospheric products using a simplified process-based model.

• The dataset is available through Google Earth Engine and is provided by Seoul National University.

• It's licensed under CC-BY-4.0 and is useful for studies on evapotranspiration, GPP, and radiation.

Description

Breathing Earth System Simulator (BESS) is a simplified process-based model that couples atmosphere and canopy radiative transfers, canopy photosynthesis, transpiration, and energy balance. It couples an atmospheric radiative transfer model and artificial neural network with forcings from MODIS atmospheric products to generate 5-km daily products.
