Figure 4: The relationship between sampling interval and error in our mean summer temperature estimates for in situ sampled lakes.

From: A global database of lake surface temperatures collected by in situ and satellite methods from 1985–2009

Figure 4

A sampling interval of 1 indicates that temperature measurements were collected daily, while an interval of 34 indicates one temperature measurement every 34 days. Temperature measurements collected with a sampling interval of 1 were considered to have no error and served as a basis for comparison with data collected at higher sampling intervals.
