1. Introduction
The first part of this document describes the Vaisala BioCover™ material. Test results are given for the estimated disintegration times of the cover, insulation, fasteners and unwinder pin in different environments. The unwinder string material is also biodegradable, and the properties of the string, Vaisala BioTwine™, are discussed separately in the white paper “Vaisala Radiosonde RS41 Unwinder with BioTwine™” B212511EN-A.
Furthermore, as will be shown in the second part, the measurement accuracy of the radiosonde is not affected at all by the change of the cover mechanics. All specifications and previouslypublished performance white papers of Vaisala Radiosonde RS41 therefore still apply.
