FIRE/SRB Wisconsin: Down-Welled Longwave Radiation, October-November 1986

Five ground stations in Wisconsin collected minute-by-minute measurements of down-welled global longwave hemispherical radiation for a 22-day period. The dataset supports research into the Earth's radiation budget and cloud-atmosphere interactions during the First ISCCP Regional Experiment. Data from stations at Fort McCoy, Stevens Point, Baraboo, Adams County, and Wautoma provide localized surface observations.

Use Cases

• Validating satellite-based longwave radiation retrievals based on high-temporal-resolution ground measurements.
• Analyzing diurnal and day-to-day variability of atmospheric longwave radiation based on minute-level time series data.
• Studying the spatial distribution of surface radiative fluxes across five distinct Wisconsin sites.
• Investigating cloud radiative forcing during the FIRE Cirrus 1 experiment period in late 1986.

Strengths

• Provides high-temporal-resolution data with measurements recorded every minute.
• Covers a specific 22-day experimental period from October 12 to November 2, 1986.
• Includes geographically distributed data from five precisely located ground stations in Wisconsin.

Limitations

• Column names and data schema are not specified in the available metadata.
• Sources conflict on the last updated date (1986-11-02 vs. 2026-04-10), suggesting potential metadata issues.
• The dataset's size and total row count are unknown.
