      The diurnal temperature range (DTR) (or difference between the maximum and minimum temperature within a day) is one of many climate parameters that affects health, agriculture and society. Understanding how DTR evolves ...
    • How much snow falls in the world's mountains? A first look at mountain snowfall estimates in A-train observations and reanalyses 

      Daloz, Anne Sophie; Mateling, Marian; L'Ecuyer, Tristan; Kulie, Mark; Wood, Norman B.; Durand, Mikael; Wrzesien, Melissa; Stjern, Camilla Weum; Dimri, Ashok P. (Journal article; Peer reviewed, 2020)
      CloudSat estimates that 1773 km3 of snow falls, on average, each year over the world's mountains. This amounts to 5 % of the global snowfall accumulations. This study synthetizes mountain snowfall estimates over the four ...
