Daymet now available in the Fixed Sites Tool

Fixed Sites Subsets Tool for North America Now Includes Daymet Data

A site within the National Ecological Observatory Network demonstrates that Daymet data can now be accessed using the Fixed Sites Subsets Tool.

For study sites in North America, Daymet daily weather data is now provided alongside pre-processed MODIS and VIIRS data subsets.

Daymet Goodness-of-Fit Statistics for 2017

Daymet station-level cross-validation statistics for year 2016

Station-level cross validation of Daymet at weather station locations showing annual mean absolute error (MAE; degrees C) for the variable maximum temperature (tmax) in 2016.

Daymet provides information to access the accuracy and uncertainty of modeled climate data at each ground station location or two-degree tile.

Daymet Climatologies Updated

Daymet V3 average annual minimum temperature for 1980 and 2015

Daymet V3 average annual minimum temperature for 1980 and 2015 for a subset of the Daymet domain in Alaska and western Canada.

Daymet V3 annual and monthly climatologies for minimum and maximum temperature, precipitation, and vapor pressure have been updated to include year 2017.

What is New in Daymet 2017?

Daymet single pixel downloads accessed the week of August 14, 2017.

Daymet single pixel downloads in the vicinity of Yellowstone National Park, USA, accessed the week of August 14, 2017.

Daymet now includes gridded climate data through year 2017 and a redesigned data extraction tool.

Calculate Climate Anomalies from Daymet

Climate normal and anomaly calculated from Daymet

Climate anomaly (right panel) in minimum daily temperature for year 1990 compared to the long-term normal (left panel). The climate normal and anomaly were calculated for a single 2-degree tile from the Daymet dataset.

New Jupyter notebook tutorials show how to access and visualize Daymet climate data from within Python and how to calculate climate normals and anomalies.
