### Summary

    The mean annual temperature raster dataset represents the average of the 12 mean monthly temperatures over the year. Mean annual temperature was calculated using the CHELSA climatology (1981–2010). The dataset was processed and harmonized for integration with the map layers of the CEC North American Environmental Atlas.

### Description

    The North American climate data were derived from the CHELSA V2.1 bioclimatic variables dataset, which is produced using a mechanistic, terrain-informed climate downscaling framework that generates high-resolution gridded temperature, precipitation, and related climate variables. The original global dataset was developed by the Climatologies at High Resolution for the Earth’s Land Surface Areas (CHELSA) initiative at the Swiss Federal Research Institute WSL (Land Change Science group). The global CHELSA bioclimatic dataset was created by downscaling global reanalysis and climate model data to a spatial resolution of approximately 30 arcseconds (~1 km). The approach applies physically based, terrain-aware algorithms that explicitly account for orographic effects, atmospheric lapse rates, and wind-driven processes. Monthly temperature and precipitation layers are first generated from bias-corrected reanalysis inputs and then aggregated into bioclimatic variables that summarize annual means, seasonality, and climatic extremes for ecological and environmental applications.For the North American Environmental Atlas, the continental subset was extracted from the global dataset and reprojected to the standard Lambert Azimuthal Equal Area projection used by the Atlas.Additional technical details on the downscaling methods and derived climate predictors are provided in: Brun, P., Zimmermann, N. E., Hari, C., Pellissier, L., & Karger, D. N. (2022). Global climate-related predictors at kilometer resolution for the past and future.

Supplemental information

      The Commission for Environmental Cooperation (CEC) is an international organization created by Canada, Mexico, and the United States of America under the North American Agreement on Environmental Cooperation (NAAEC), which came into force at the same time as the North American Free Trade Agreement (NAFTA). The CEC was established to address regional environmental concerns, help prevent potential trade and environmental conflicts, and to promote the effective enforcement of environmental law. As of 2020, the CEC operates in accordance with the Environmental Cooperation Agreement, which entered into force at the same time as the CUSMA/T-MEC/USMCA trade agreement.

    Measure description

          A spatial completeness assessment was conducted after extracting the North American extent and reprojecting the CHELSA BIO1 raster to the standard Lambert Azimuthal Equal Area projection. The dataset was inspected for NoData values, edge artifacts, and cell misalignment introduced during reprojection. Cell counts and value ranges were verified to ensure no unintended omissions occurred. The final raster exhibits continuous coverage across the defined terrestrial extent, with NoData values limited to areas outside the land mask.

Process step ▼►
  When the process occurred2026-02-18 00:00:00
  Description

        The CHELSA BIO1 (Mean Annual Temperature, 1981–2010) global raster was clipped to the North American region using the CEC North American Political Boundaries vector dataset. The clipping was performed using the Extract by Mask tool in ArcGIS Pro. During this process, the raster was reprojected to the Lambert Azimuthal Equal Area projection (the standard coordinate reference system used for the CEC North American Environmental Atlas). The data were resampled from the original ~30 arcsecond (~1 km) resolution to a 1 km cell size, aligned with Version 1.0 of the CEC North American Mean Annual Temperature raster layer to ensure consistency in grid structure and spatial resolution.

  Description

        Pixel values were converted from scaled Kelvin to Celsius according to the scale factor and offset specified in the CHELSA BIO1 technical documentation. The transformation was performed by multiplying the raster values by 0.1 (scale factor) and subtracting 273.15 (offset). This conversion was implemented using the Raster Calculator tool.

  Description

        CHELSA BIO1 (Mean Annual Temperature) is a globally gridded climate layer at ~30 arcsecond (~1 km) spatial resolution derived from mechanistically downscaled temperature data. The dataset is based on bias-corrected reanalysis inputs and terrain-aware modeling that accounts for elevation-dependent lapse rates and orographic effects. BIO1 represents the average of the 12 monthly mean temperatures for the 1981–2010 climatological period and is intended to support ecological, environmental, and climate impact analyses.
