1 Risvollan: 1. Status 2. New equipment /upgrades Name, title of the presentation

2 Precipitation • FUESS: broken (destroyed beyond repair it looks like) • Lambrecht: operational, recorded by NVE

3 Air properties • Temperature: works w/signal to NTNU, but could probably need calibration check • RH: works w/signal to NTNU, but could probably need calibration check

4 Radiation and wind • Radaiation: destroyed beyond repair • Wind: broken, maybe possible to repair if it is only the top plastic piece

5 Water • Sewer: appears to work, signal to NTNU ok. Unknown status of maintenance. Manual recorder stopped – appeared not in operation since February 2010. • Stormwater: appears to work, both signals to NTNU ok (float and ultrasound), needs calibration/cleaning Manual recorder stopped – appeared not in operation since February 2010. • Snowmelt: appears to work, signal to NTNU ok (pressure cell), needs calibration/cleaning.

7 Data aquisition system • DSU: records data, but found DUS units from as far back as January laying up there, so unsure if the series are complete. Brit downloads, but does not check data. • PC/Lab. View – works, turned it on and it started recording data, but currently not in operation. Probably needs some servicing/updating. • Communication: telephone and internet access works
