Global Freeze–Thaw Cycles (Mean Annual Count) ERA5
Interactive map with scientific data analysis, point lookup, and detailed environmental information
Map Information
This raster represents the mean annual number of freeze–thaw cycles over the period 2020–2024, derived from ERA5 reanalysis data. A freeze–thaw cycle is defined as a day in which the daily minimum air temperature falls below 0 °C (273.15 K) and the daily maximum air temperature exceeds 0 °C.

Description: This raster represents the mean annual number of freeze–thaw cycles over the period 2020–2024, derived from ERA5 reanalysis data. A freeze–thaw cycle is defined as a day in which the daily minimum air temperature falls below 0 °C (273.15 K) and the daily maximum air temperature exceeds 0 °C.
Annual freeze–thaw counts are calculated for each year using daily minimum and maximum 2-meter air temperature fields and averaged across the five-year period (2020–2024) to produce a representative climatological surface.
The output has been resampled from the native ERA5 grid to a global geographic grid at 0.008333333333 degrees (~30 arc-seconds, approximately 1 km at the equator) in GCS_WGS_1984.
This dataset is intended to characterize environmental stress mechanisms such as thermal expansion, material fatigue, soil heave potential, and infrastructure durability.
