GBON compliance: tightened criteria for availability
“Does a station exist
and is it regularly
exchanging data on
a daily basis?”
“Is a station meeting
minimum GBON
requirements, to
make a significant
leap in forecast skill?”
SOFF additionality principle, baseline and exemption
“An intervention may be described as 
additional

otherwise have occur

  4. GBON compliance: WDQMS today GBON surface stations GBON upper air stations

  5. GBON compliance: tightened criteria for availability GBON compliance 2023- Global gap 2022 Is a station meeting minimum GBON requirements, to make a significant leap in forecast skill? Does a station exist and is it regularly exchanging data on a daily basis? Monthly Availability (%) 30% 80% (on 60% of days) Timeliness (%) < 5% < 5% Monthly Quality (%) Complete profile (for upper air) < 5% < 5% yes yes
