This document describes the format of the data files in the GRUAN Data Product (GDP) of the RS41 radiosonde. GDPs are stored in NetCDF files. The data fields and attributes within the RS41 radiosonde NetCDF files are comprehensively explained in this document. The GDP includes raw data, processed data, uncertainty estimates, and selected meta data.

The measurement practice of GRUAN-compliant radiosoundings as well as the algorithms for correction and processing of the raw data including the underlying motivations, assumptions, and uncertainty considerations are extensively described in the main RS41 Technical Document (GRUAN-TD-8).

In this version of the document, the release version 1 of the RS41 GRUAN Data Product (RS41-GDP.1), which is in operational use since 2021-11-09 (release date), is described.
