Abstract
For two upper-air stations in Kamchatka for the period 2005-2014 the values of instability indices LIFT, TOTL and KIND, obtained by upper-air sounding and product MOD07_L2 of spectroradiometer MODIS were compared. These stations were chosen because the difference in observation time does not exceed one hour. It was found that the measurements performed at one time have a much better agreement than those different by a few hours. The most consistent and uniform were the TOTL and KIND values obtained at 12 UTC. Data from the MOD07_L2 are promising for developing new methods of diagnosis and prediction of the spatial arrangement and dynamics of convective clusters.
