1 Temperature coupling in arctic ground Estimation of time delay
Abstract—This paper estimates the penetration speed of air temperature into the top layers of the ground surface in Alaska. It shows that the delay is a function of depth. One of the observed areas revealed an unexpected air temperature frequency with a period of 28 days. The penetration of this unk...

| Summary: | Abstract—This paper estimates the penetration speed of air temperature into the top layers of the ground surface in Alaska. It shows that the delay is a function of depth. One of the observed areas revealed an unexpected air temperature frequency with a period of 28 days. The penetration of this unknown frequency component was confirmed by measurements in the top 10 cm of the surface. midnight over a collection period between 1997-08-7 and 2001-10-31. The time axis of the data was converted into a linear day scale with origin at 1997-1-1. |
