The LAPrec dataset is provided in NetCDF format, following the CF-1.6 convention (see http://cfconventions.org/cf-conventions/v1.6.0/cf-conventions.html). Besides the monthly precipitation fields, fields of geographical variables (longitude, longitude and elevation above sea level) and details on the coordinate reference system are included. The fields consist of a regular 5 km x km grid that is spatially referenced in ETRS89 / ETRS-LAEA (European Terrestrial Reference System 1989-Lambert Azimuthal Equal Area, see https://spatialreference.org/ref/epsg/3035/).
Two variants of the dataset exist reflecting the two different starting dates (January 1871 and January 1901) and respective different station numbers (currently 85 and 164). Updates of the dataset might change the exact number of ingoing stations but keep three criteria for missing data defined in chapter 1.1. as well as the starting years 1871 and 1901. Homogenised station series data (no deliverable of this contract) are available from the HISTALP database of ZAMG and according files. In principle, the station series are updated annually. Due to national issues, the timing of the update varies within the year.
Versioning of the LAPrec dataset is in the format vX.Y where an increment of X denotes methodical adaptations and an increment in Y denotes updates in input station data. The file names consist of the dataset acronym, the starting year and the version number, e. g. LAPrec1871.v1.0.nc and LAPrec1901.v1.0.nc.
