Humboldt Bay GCM Climate Projections

This data represents GCMs from 3 different datasets. All data has been clipped or aggregated to the Humboldt NFWR Extent.

Climate Variables

ClimateNA variables include annual, seasonal (biological), and monthly metrics. There is a significant amount of overlap (i.e., seasonal bioclimatic variables exist as well as annual bioclimatic variables).

The following table gives all abbreviations and definitions. Standard format for appended variables is as follows:

  • 'at' : Autumn (Sep-Nov)
  • 'wt' : Winter (Dec-Feb)
  • 'sp' : spring (Apr-May)
  • 'sm' : summer (Jun-Aug)
  • 'mean' : mean value
  • 'sd' : standard deviation
  • 'se' : standard error
Climate NA points and Polygon Extent

This web application uses data from BIOCLIM, Climate NA, and CMIP5 datasets. Standard error bars have been included for each variable set. Keep in mind that BIOCLIM and CMIP5 data represent temporal variability of these GCM data, whereas ClimateNA represents spatial variability within the refuge for these GCM data. BIOCLIM has been downscaled at a 4km scale and was derived from PRISM data (see weblinks below). ClimateNA uses an elevational driven downscaling with PRISM, and is based on CMIP5 GCM models. CMIP5 has been downscaled to a 4km scale. This is part of a collaborative project with the Southwest Climate Science Group, UC Davis (JMIE) and USFWS. This data is subject to change and is only meant for visualization and comparison purposes. The plots are downloadable if you right click in or on the plot and "save image".
