27-06-2016 Woburn met data: The Woburn Met Station Datalogger has now been replaced and is recording the data. However, the Cup Anemometer which records Wind Speed is not currently working. This will not be replaced until early August. All the other met data is being recorded, but we are currently unable to communicate with the datalogger, so the data is not being loaded into e-RA. We will correct this as soon as possible, and then up load the missing data. Currently there is no Woburn met data in e-RA after June 7th. 13-06-2016 Woburn met data: Following storms last Tuesday (7th June) we lost communication with the Woburn Met Station. The storm actually took out the BT phone lines with a power surge over the system causing considerable damage to phones and modems at Woburn Farm. Unfortunately this power surge has caused damage to the Woburn datalogger. Because of this we are unable to collect weather data at Woburn. We hope that a new datalogger will be installed at the end of this week. Currently all the Woburn met data after June 7th 2016 is missing.
