DESCRIPTION:\n\nWorkshop description\n\nInternational and national regulat
 ion governs the allocation of microwave spectrum for a range of purposes\,
  including earth system science including weather prediction and climate m
 onitoring. There are many competing and important application areas. For r
 egulators to make an informed decision about allocations\, including maint
 aining existing allocations\, they need up to date and well documented evi
 dence of the economic and societal value of the bands in different applica
 tion areas. This workshop will provide an opportunity to re-examine these 
 economic and societal values.\n\nOperational and research applications in 
 meteorology\, climate and hydrology have many requirements\, and a number 
 of bands are allocated exclusively to this\, with many more having a share
 d allocation with other applications. These include bands for: telecommuni
 cation to share meteorological observations\, including conventional and s
 atellite observations\; active remote sensing e.g. weather radar\, radio o
 ccultation\, scatterometer and SAR\; passive applications e.g. microwave s
 ounders and imagers.\n\nPeriodically NWP centres measure the value of all 
 these data types in terms of forecast skill and results are shared\, for e
 xample through the WMO Observation System Experiment workshops organised b
 y the WMO expert team\, C-SEIS (Coordinators on Scientific Evaluation of I
 mpact Studies). However the additional steps to estimate individually the 
 impact of specific bands is done less often and furthermore the step to tu
 rn impact on forecast skill into economic and societal impact is itself di
 fficult. These additional steps are needed to give frequency managers and 
 regulators information about the value to earth science when band allocati
 ons are discussed. It can not be assumed that the value of numerical weath
 er forecasts\, and is reliance on microwave spectrum\, is self-evident.\n\
 nIn this short workshop we invited Centres to provide their latest informa
 tion\, presented as concisely as possible\, and then discussed the steps t
 o produce an up to date and thorough account of the value of these bands. 
 Further to discuss how such a document can be maintained and kept up to da
 te. The output of the workshop was therefore a plan to create this documen
 t\, with some of the inputs needed already identified\, and commitments to
  provide the remainder.\n\nhttps://events.ecmwf.int/event/96/
