Fleming meteorological station was added to the McMurdo Dry Valley network in the 1995-1996 field season. It was established on the shore of Mt. Fleming in Victoria Valley, one of the largest lakes in the dry valleys, recently discovered to have a 19 m ice cover over a hypersaline brine of undetermined depth. The station was set up to sample sensors every 30 seconds and send summary statistics (for example, averages and maximums) to solid-state storage modules every 15 minutes. This has resulted in approximately 20 values being recorded for final storage in every output interval.

Program Name: flm201011v1.dld Sampling every 30 seconds. Cr10X 1 minutes and 12 secs behind. Adjusted time at 12/14/2011 1442. Swapped wind monitor, RH head, CR10X and pressure. Installed FGR-115RC radio, wavelink PRO890-12-40F02N4 12 dbi antenna, Crydom solid-state relay DC60S3 and SC32B. Antenna pointed at Lake Vanda. No connection Loaded new program, FLMM_201112v1.dld at 12/14/2011 @ 1515. For second file (FLMM_201112_SM002-003.DAT: Cr10X 2 minutes and 10 secs behind. Adjusted time at 01/26/2011 1420. Swapped out pressure with old sensor. Was not sure new one was working, which it was. Need to replace again next season. Loaded new program, FLMM_201112_v2.dld at 12/14/2011 @ 1515. Corrected mistaking in radio timing. Moved wire from C8 to C7, wrong location for turning the SwCtrl12V. Rotated radio antenna 10 degrees CW. Still no success connecting with the hub at Vanda Second air temp is still not working. Need to check program.
