2008 Data - Notes ----------------- AWS performed well over the winter months. A failure of a hardware module between the datalogger and modem resulted in data loss between May and October 2008. Archive of Notes from AWS log on webpage ---------------------------------------- 29/10/2008 I've remotely disabled motor for a couple of hours to thaw out the instruments - winter's here already - this will flag up as a fault, but it isn't. 17/10/2008 Visit to summit - mechanism OK. Replaced datalogger-GSM interface, hope that will solve communications problem. Plan to replace logger battery on next visit, and try to re-instate radio link to Glenmore Lodge. However not 100% sure comms link is fully up and running. Thermometer fan needs replaced so T2 reading high - T1 should be OK. Replacement camera on site, but think there remains a problem, so this will probably remain offline. 1/8/2008 Visit to summit - mechanism OK, but communications link problem unresolved - not a simple wiring fault. Will be investigating further to try to resolve comms link problem. Camera returned to HW for upgrade. 21/5/2008 Possible comms problem - modem is connecting with summit, but no connection to logger. Possibly just a dislodged cable? Will check on next visit. 27/4/2008 Low summit windspeed, so T1 is reading high and should be ignored. T2 seems OK. 9/4/2008 T1 reading high if windspeed below ~20mph. Suspect air circulation fan failure on T1. T2 should be OK. 18/2/08 Network issues resolved - data back online 16/2/08 Local network problems - there will be no data posted on the internet until these are resolved, sorry. 16-17/2/08 2000hrs-0200hrs Temperature fluctuations of ~3~5C per 30 mins! Probably due to inversion layer boundary at summit. 11-16/2/08 Fantastic weather - temperature inversion so +ve temperatures are real! 11/1/08 Looks like AWS fault has cleared itself, and is working OK at present! I've a number of replacement switches on order, which will be swapped on next visit. At present Camera is offline - I need to do some work on the summit computer, which requires a summit visit. 7/1/08 AWS fault developed on 6th Jan - looks like its stuck closed. Will be offline until next maintainance trip.
