This GRUAN relevant paper was published. Please have a look on the following abstract.
Attached is a document describing the requirements for GRUAN station regarding the pre-launch procedures for routine soundings with Vaisala RS92 radiosondes. In order to obtain high data quality, ensure long term stability, and to make sure that measurement uncertainties are within the ranges that are reported in the product files, it is important that some ground checks are made before launch in the way described in this document and that the meta-data are reported to the GRUAN lead centre.
The lead centre has prepared a collection scheme for meta-data related to GRUAN measurements. All information describing sites, measuring systems, and measurements will be collected with well-defined XML files and stored in a meta-data base at the lead centre. There are comfortable tools available programmed in Java for generating and submitting the GRUAN meta-data (GMD) files.
The GRUAN Analsyis Team for Network Design and Operations Research (GATNDOR) held its first post-ICM2 quarterly conference call on April 12, 2010 at 10 AM EDT (-4 UTC). The main business of the meeting was to solidify the new membership roster, refine the active research topics, and share plans for executing the work up to the next conference call.
The paper “A guide for upper-air reference measurements” by F. Immler, J. Dykema, T. Gardiner, D. N. Whiteman, P. W. Thorne, and H. Vömel went online on the interactive Journal “Atmospheric Measurement Techniques” where it is open for public discussion for eight weeks (link).
