Weather conditions on Plateau de Bure

Figure 3 shows the water vapor content measured on Plateau de Bure between Nov 5 and Nov 7 (the various curves correspond to the different antennas). Very low water vapor content (less than 0.7 mm) persisted when the outside temperature was about -12 degrees. With the upcoming of warmer air (about 0 degrees), the water vapor content increased to about 3 mm.

Water vapor content well below 2mm is expected to occur frequently in winter, since the mean outside temperature is -10 degrees.
