To assess a species' vulnerability to climate change, we commonly use
mapped environmental data that are coarsely resolved in time and space.
Coarsely resolved temperature data are typically inaccurate at predicting
temperatures in microhabitats used by an organism and may also exhibit
spatial bias in topographically complex areas. One consequence of these
inaccuracies is that coarsely resolved layers may predict thermal regimes
at a site that exceed species' known thermal limits. In this study,
we use statistical downscaling to account for environmental factors and
develop high-resolution estimates of daily maximum temperatures for a 36
000 km2 study area over a 38-year period. We then demonstrate that this
statistical downscaling provides temperature estimates that consistently
place focal species within their fundamental thermal niche, whereas
coarsely resolved layers do not. Our results highlight the need for
incorporation of fine-scale weather data into species' vulnerability
analyses and demonstrate that a statistical downscaling approach can yield
biologically relevant estimates of thermal regimes.

seven species of microhylid frog. Max temperatures only are given for
AWAP. Max and min temperatures are provided for downscaled air
temperatures (DS1), both of which are necessary to calculate under-log
daily max temperature (DS2). Each point of occurrence has 4 temperature
records (AWAP, DS1 Tmax, DS1 Tmin, and DS2) for every day of the year
