FLASHFlux: Daily Gridded Satellite Top-of-Atmosphere and Surface Radiative Fluxes

FLASHFlux Version 4A provides low-latency (< 7 days from observation) gridded radiative flux data from NASA's Terra and Aqua satellites. This rapid-release product, derived from the CERES project, combines instantaneous scanner data with high-resolution MODIS imagery and GEOS-5 atmospheric models. It is designed for applied science and education, offering parameterized surface and cloud flux estimates without the six-month processing delay typical for climate-quality CERES data.

Use Cases

• Modeling short-term atmospheric energy budgets based on gridded Top-of-Atmosphere (TOA) shortwave, longwave, and net fluxes.
• Analyzing cloud radiative effects based on cloud properties derived from MODIS imagery.
• Estimating surface radiative fluxes for energy balance studies using the Langley parameterized algorithms.
• Monitoring rapid changes in Earth's radiation budget for weather and climate applications.

Strengths

• Data latency is less than 7 days from observation, enabling near-real-time analysis.
• Integrates data from multiple sources: CERES instruments, MODIS imagers, and the GEOS-5 ADAS.
• Product is actively maintained, with a last update recorded in March 2026.

Limitations

• The product is explicitly not intended to achieve climate data quality, with some calibration accuracy relaxed for speed.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
