IAGOS central database hosted by ETHER (CNES-CNRS/INSU)
IAGOS is a new European Research Infrastructure conducting longterm
observations of atmospheric composition, aerosol and cloud particles on a
global scale from commercial aircraft of internationally operating
observations (August 1994 - November 2014) are airborne in-situ measurements for ozone, water
vapor, carbon monoxide, and total nitrogen oxides (NOy).
Measurements are geo-localized (latitude, longitude and pressure)
and come with meteorological observations (wind direction and force,
temperature). Data acquisition is automatically performed during
round-trip international flights (ascent, descent and cruise phases)
from Europe to America, Africa,
Middle East, and Asia.
IAGOS observations (July 2011 - today) include ozone, water vapor, carbon monoxide, and cloud droplets (number and size). Depending of the optional
measurements are either, nitrogen oxides (NOx),
or total nitrogen oxides (NOy),
or greenhouse gases (CO2
or aerosols. Since July 2011, the first IAGOS-equipped aircraft
flies the basic instrumentation, plus an optional instrumentation for
products are the height of the dynamical tropopause at the
aircraft position and backward trajectories of air masses sampled
along the flight tracks.
and IAGOS data policies are free access for scientific use (WMO resolution 40
for policy and practice for the exchange of meteorological and
related data and products). Users have to sign the IAGOS data
protocol and to fill online a form for getting
is a joint venture between CNES and CNRS/INSU to promote the use of
in-situ and satellite observations for atmospheric chemistry. More detail here.
