Table 1: Pairs of images used as input data. \(\Delta t\) is the time window between the two images (days), and \(SNR_{AVE}\) is the mean signal to noise ratio. for the purpose of linking climate variation to PMG dynamics. The unique available meteorological dataset at the glacier surface that we know of covers a very short time period, namely, [PERSON] (2019), which measured monthly temperatures at the glacier front from 1996 to 1998.
