Monthly trends in grazing land condition ratings (measured as the CCIndex) over the 1995–2022 period. Browns represent declining grazing land conditions while greens represent improving conditions. Hatching is statistical significance at the 95% confidence level. Image adapted from Bundy et al. (2025).

Image of web interface looking at Global Historical Climatology Network daily (GHCNd) data with example downloading a small region of data in southeast Minnesota. In the map, a user can define a bounding box (blue-square). Then in the application programming interface (API) call, the user can define the climate variable, the dates for which the data should be gathered and the type of aggregation that is requested. Image from Gall et al. (2024).
