Daily observations in 1km*1km grid
Daily weather station observations have been interpolated into 1km*1km grid using external predictors (e.g., elevation) as covariates (kriging with external drift KED).

Daily data is in annual netcdf files. The files are produced by R:s Raster package.
Data will be updated once a year until Jan 2022 and after 8.2.2022 once a month (day number 8 each month)

Accessing the Data on AWS
The data is uploaded into an AWS S3 Bucket:
Files are named with a convention (using all lower case letters):
The data is stored with the following prefixes:
For example the file that contains the interpolated snow depth values for the year 1985 has the key
