We know what the current state of the atmosphere is more or less, from piecing together a series of surface and
upper air observations that may come from ground - based weather stations, balloons, aircraft, and satellites.

upper ocean dynamics and
air - sea interaction; investigation of the ocean's role in climate; sustained climate - quality
observations in and at the surface of the ocean; innovative ocean
observations.
Forest et al. 2006 compares
observations of multiple surface,
upper air and deep - ocean temperature changes with simulations thereof by the MIT 2D climate model run at many climate parameter settings.
There are three likelihood functions involved, one for each of the three «diagnostics» — surface,
upper -
air, and deep - ocean, which involve respectively 20, 218 and 1
observation (s).
I have long maintained that
upper -
air runs, even before computers took over, were far more accurate that any other readily available weather
observations.
Develop and validate retrieval algorithms for ocean and sea ice parameters from various satellite Earth
observation data, which in are used in studies of
upper layer mesoscale ocean processes,
air - sea - ice interaction, climate change studies and in operational oceanography.
We put together an analysis using
upper -
air observations, or wind
observations, in the lowest 12 km (7.5 miles) of the atmosphere.
Thus, I think we all should be able to agree, that unless the
upper -
air observations are wrong, the observed trend in atmospheric stability over the tropical Atlantic is in a sense opposite to direction that models suggest it will be, at least into the future.
In addition to weather
observations we monitor e.g.
air quality, radioactivity and properties of the
upper atmosphere.
The atmosphere ECV breakout group was asked to consider 10 ECVs related to
observations of the atmosphere: Earth radiation budget (including solar irradiance); aerosol properties; ozone; carbon dioxide, methane, and other greenhouse gases; cloud properties; precipitation; water vapor; surface wind speed and direction;
upper -
air wind; and
upper -
air temperature.
