developing GRUAN data productsThe accurate monitoring of climate change imposes strict
requirements upon observing systems, in particular regarding
measurement accuracy and long-term stability. Currently available
data records of the essential climate variables (temperature-T ,
geopotential-p , humidity-RH, wind, and cloud properties) in the
upper-air generally fail to fulfil such requirements. This raises
serious issues about the ability to detect, quantify and understand
recent climate changes and their causes. GCOS is currently
implementing a Reference Upper-Air Network (GRUAN) in order to fill
this major void within the global observing system. As part of the
GRUAN implementation plan we provide herein fundamental guidelines
for establishing and maintaining reference quality atmospheric
observations which are based on principal concepts of metrology, in
particular traceability. It is argued that the detailed analysis of
the uncertainty budget of a measurement technique is the critical
step for achieving this goal [...]doi:10.5194/amt-3-1217-2010Long term observationsLocal observationsSupersitesCESARLong term observationsLocal observationsVariable groupsAtmospheric stateLong term observationsLocal observationsInstrument groupsTower & Sondes product metadata for data in this file station_details metadata for site gruan_processor global attribute data from original GRUAN datafile time time time seconds since 1970-01-01 00:00:00 00:00 lat time latitude degree_north lon time longitude degree_east zsl time altitude m zg time geopotential_height m pa time air_pressure Pa ta time air_temperature K hur time relative_humidity 1 wspeed time wind_speed m s-1 wdir time wind_from_direction degrees_North ta_error time air_temperature standard_error K zsl_error time altitude standard_error m pa_error time air_pressure standard_error Pa hur_error time relative_humidity standard_error 1 wdir_error time wind_from_direction standard_error degree wspeed_error time wind_speed standard_error m s-1
