End of Dezember 2015 an automatic weather station was installed on the Filchner Ice Shelf  (-80.43681, -044.43199) 105 m above sea level. The installation took place in the framework of the international Filchner Ice Shelf Project FISP.The huge Filchner Ice Shelf is bordered to the west by the Berkner Island and to the east Coats Land.

The minutely averages of the data acquisition get transfered to AWI Bremerhaven via IRIDIUM and visualized on this web page as promt as possible, see below. Additional, the data get used to perform hourly synoptic weather reports  which get coded according to the  FM-12 code and distributed in the GTS under the WMO# 89047. Since the IRIDIUM transfer is not working propperly for 100% all minutely averages get stored inside the AWS as backup.

The transmitted data show that the AWS Filchner is situated in a rather calm region. Quite seldom the wind exceeds the threshold velocity from the wind turbine (about 10 m/s ). Thus, the battery voltages is decreasing since the beginning of the polar night. An outage of the AWS must be expected within the coming weeks. During the comming summer season, a wind turbine with a lower threshold will be installed.
