DESCRIPTION:\nOverview\nCloud and precipitation are some of the most impor
 tant parameters in any forecast\, yet they remain challenging to observe\,
  model and predict. Our main source of observations is satellite measureme
 nts of the Earth's thermal radiation\, reflected sunlight\, and backscatte
 red radar and lidar. Cloud and precipitation particles interact with this 
 radiation through thermal absorption and scattering\, which is strongly de
 pendent on the shape\, size and composition of individual cloud particles\
 , and varies strongly with frequency. From this highly indirect informatio
 n\, we can only infer profiles of cloud and precipitation by combining the
 se observations with models of atmospheric dynamics\, cloud\, precipitatio
 n and radiative transfer. But these models remain simplified\, incomplete\
 , and prone to systematic error. If we could reduce these errors\, cloud a
 nd precipitation forecasts could be much improved. Therefore\, the challen
 ge in using cloud and precipitation observations is not just to use them t
 o initialise forecasts\, but to use them to improve the models themselves.
  \nThrough a series of invited talks\, this workshop will first review th
 e state of the art in using cloud and precipitation observations\, from th
 e satellites to forecast and everything in between. Working group discussi
 ons will then try to inform future developments\, considering questions su
 ch as: \n\nWhich cloud and precipitation observation types need more deve
 lopment\, considering both future missions and existing data that is insuf
 ficient or under-exploited? \nHow can we combine information from active 
 and passive observations\, and from spectral regions from the microwave to
  the solar\, to best effect? \nHow do we start inferring not just cloud a
 nd precipitation parameters\, but equations and even models\, from the obs
 ervations? \nWhat developments in physical modelling and data assimilatio
 n are needed to make better use of these observations? \nHow can machine 
 learning and AI help? \n\nAttendance\nThis workshop will be held in-perso
 n only and attendance is by invitation. If you have received an invitation
  and would like to attend\, please complete the registration form before 
 28 September 2026.\nIf you would like to be considered for an invitation\,
