The on-going project to monitor
the health of many weather and climate observing networks will be addressing many global in situ networks.
- Health of the GCOS Upper Air Network (GUAN)
The GUAN is a global
network of stations that measure the free atmosphere by regularly
launching instrumented balloons. A subset of the full radiosonde network, GUAN stations were
selected based on their spatial distribution and length and quality of
their historical observations.
- Health of the GCOS Surface Network (GSN)
The GSN stations are a
collection of the highest quality and longest operating surface weather
observing stations in the world. These stations provide daily and monthly observations which are
used to monitor the global climate.
Global in situ networks to be addressed in the
future:
- The Volunteer Observing Ships Network (VOS)
Mariners have been
systematically taking observations of the weather and sea conditions,
including sea surface temperatures, since 1853. This network continues to operate
today with thousands of observations being taken by approximately 7,000
ships.
