Downscaled Daily 1km Climate Data (NEX-GDDP-CMIP6) for Southeast Texas

For the SETx-UIFL, the daily NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP-CMIP6) dataset climate projections were downscaled from ~27km to 1km. The SETx dataset provides very high-resolution climate data for the historical (1950-2014) and future scenarios derived from CMIP6 global models under the four Tier 1 Shared Socioeconomic Pathways (SSPs 1.26, 2.45, 3.70 & 5.85), developed for the IPCC Sixth Assessment Report.

A subset of ten NEX-GDDP-CMIP6 models was selected for SETx-UIFL to provide robust daily historical and future climate conditions in Southeast Texas. These models were chosen to represent a balance of model families, climate sensitivities, and availability across scenarios, ensuring a diverse and reliable ensemble for regional analysis. The selected models are:

  • BCC-CSM2-MR
  • CESM2
  • CMCC-ESM2
  • CNRM-ESM2-1
  • EC-Earth3
  • FGOALS-g3
  • GFDL-CM4
  • MPI-ESM1-2-HR
  • MRI-ESM2-0
  • NorESM2-MM

The following daily variables were downscaled for SETx-UIFL:

  • tasmax – Near-surface maximum air temperature
  • tasmin – Near-surface minimum air temperature
  • tas – Near-surface mean air temperature
  • pr – Daily precipitation total
  • hurs – Near-surface relative humidity
  • huss – Near-surface specific humidity
  • rsds – Surface downwelling shortwave radiation
  • rlds – Surface downwelling longwave radiation
  • sfcWind – Near-surface wind speed

These downscaled data support regional impact analysis and can also be applied in other scientific studies requiring localized climate projections. The original dataset is publicly available at: https://doi.org/10.7917/OFSG3345.
