Meteorological data

The table bellow describes all meteorological data available to us. The parameters measured are (but all variables are not available for all stations):

  • T: mean temperature, degree Celsius
  • Tmax: maximum temperature over each time bin
  • Tmax: minimum temperature over each time bin
  • RR: precipitations in mm
  • pressure: barometric pressure (hPa)
  • snow: snow height in cm
  • wind_speed: wind speed (km/h?)
  • wind_speed_max: maximum wind speed (km/h?)
  • patm: atmosheric pressure

Description of files:

We give the raw data in text format as well as matlab files. Time is given in UTC time unless scpetified otherwise. The data has been reinterpolated to fill out the gaps, and resampled with various time steps. The value '-9.99' indicates data is not available. From LGIT, all meteo data is available at /lgit/mouv-terrain/SISMO/METEO. We don't have the permission to share Meteo France data. Ask us if you want this data.

Comparison of different datasets:

Figure 1 compares the precipitation measured at Mont-Sec, Vizille, Chamrousse and Alpe d'Huez. Precipitations are lower at Alpe d'Huez, but this is partly due to the absence of data in the first 2 weeks of june 2008, when there was a lot of rain. Rain at Vizille was increased by 15% to account for the fact that this station underestimates the rain. Even with this correction, there is still a bit less rain than at Chamrousse. The different datasets for Mont-Sec are inconsistent: there is more rain in the hourly and monthly data compared to daily data!?
The temperature measured at Vizille, Chamrousse and Alpe d'Huez in shown in Figure 2 (there is no measure of temperature at Mont-Sec?). Temperature at Vizille is on average higher than in Chamrousse by 6.3°, and 7.4° higher than Alpe d'Huez, so a difference of 0.45° for a 100m chage in elevation.
