  4. GCOS “Reference” Upper AIR Network (GRUAN) Illustration of the initial set of 15 sites composing the Global Climate Observing System (GCOS) Reference Upper Air Network (GRUAN). Each site provides one or more reference radiosonde observation per week along with specified ancillary ground (lidar, MWR, FTIR …) observations. A reference observation in the context of GRUAN includes adherence to best measurement practices as specified in the GRUAN Manual and Measurement Guidelines including specification of measurement and product uncertainty. Expansion of GRUAN to up to 40 sites within the next five year is planned.

  6. Ref / Ded Sampling Strategies • Actual Propose • 3 ARM sites • Dual at SGP every 4th; annual • Combo dual / single at NSA every 4th day … (save 45 RS92) • Single at TWP every 4th day • Beltsville and PMRF provide sporadic single dedicated RS92, sporadic • AEROSE • Support 2 dedicated GRUAN sites using “saved” from ARM + JPSS budget (40K) • GRUAN (10 sites incl ARM) provide reference RS92; multiple daily, sporadic
