Data collection timeline

All data were collected from the time of deployment to our last visit on 2020-03-12. Due to the onset of the COVID-19 pandemic and our thereafter rapid departure from Patagonia, no further data were downloaded, though if the stations are intact, they likely have recorded substantial additional data.

Field Notes

1. WS1's anemometer was set north while pointing into the wind (i.e., direction wind is coming from). WS2 and WS3 were set pointing away from the wind. Correct WS2 and WS3 by 180 degrees. (AW has confirmed this by comparing installation photos in which the vane is visible with prevailing wind directions in the data.)
2. Tipping-bucket rain gauge data seems to freeze on all "1" on WS2 and WS3. Could be that the bucket is stuck in the middle. This also causes the logger to reset from time to time, but data continue to be recorded.
3. To combine multiple data files, retain the same header and merge rows.
4. On the first time step, a comma is missing near the end of the line. Include it (and note it / update the software that caused this problem).

WS-2: Buscaini

Photo during installation of the middle weather station, on a moraine near the Buscaini shelter (either ruins or it was always just a low wooden wall) but out of the forest. This is WS-2: Buscaini.

WS-3: Orloc

Photo during installation of the main mast of the upper weather station, on bedrock between Glaciar Perito Moreno and Glaciar Orloc. Some team members are pausing to photograph the spectacular view. This is WS-3: Orloc.
