In the process of meeting these objectives, we will produce spatial statistics and estimates summarizing dates of melt onset, dates of freeze-up, melt duration, dates of first snow cover and snow-free conditions, and duration of continuous snow cover. We will also assess significance of multivariate trends in terms of large-scale climatic forcings versus localized, weakly correlated weather conditions. In addition, we will intercalibrate between the various passive microwave (SMMR, SSM/I, and AMSR-E) and the optical and thermal sensors (AVHRR and MODIS) using the EOS era sensors as the baseline. These objectives will also help us summarize statistics and trends for a suite of cryospheric variables and related atmospheric conditions.
