All GRUAN data products are based on measurements and processing that
adhere to the GRUAN principles (e.g. Immler 2010).

The GRUAN data product (RS92-GDP) currently available is based on 
radiosonde measurements using Vaisala RS92 instruments. In the future
more data will be provided by GRUAN, including products based on 
other in-situ or remote sensing instruments.

Please sign up for our GRUAN data user service (registration), if you
are interested in GRUAN data products. You will then receive occasional
updates and news about GRUAN data products as they become available.

All GRUAN data products can be accessed openly.

Please consider including GRUAN scientists as co-authors for 
publications in which GRUAN data play a substantial role or are 
extensively used.

Please do not hesitate to contact the GRUAN Lead Centre 
(mailto:gruan.lc@dwd.de) if you have questions about data quality 
and/or suitability of the data for the specific study in question and
