A note on ground thermal regimes and global solar radiation at 4720 m a.s.l., High Andes of Argentina
Abstract The near‐surface ground thermal regime at 4720 m a.s.l. is described and assessed in terms of its daily and annual fluctuations (frost cycles, freezing and thawing depths, etc.). Correlation between solar radiation and soil temperature in the uppermost parts of the soil is caused by intense...

| Summary: | Abstract The near‐surface ground thermal regime at 4720 m a.s.l. is described and assessed in terms of its daily and annual fluctuations (frost cycles, freezing and thawing depths, etc.). Correlation between solar radiation and soil temperature in the uppermost parts of the soil is caused by intense radiation (mean annual value of 22.3 MJ m −2 d −1 ). Surface soil temperatures show an enormous amplitude (>50 °C in a depth of O.1 m) and frost cycles occur almost throughout the year. The seasonally frozen ground extends to only 1.5 m in depth. |
