Dear all,
within the frame of the IGAS project (IAGOS for Copernicus Atmospheric
Service, http://www.igas-project.org
<http://www.igas-project.org/index.php/ProjectInfo/ProjectInformation>)
we would like to propose 5 new CF standard names:
*standard_name*
*units*
*definition**
*
size_resolved_number_concentration_of_dry_aerosol_in_air
m-3
Size resolved denotes the capability of an instrument to measure
aerosol properties in different size ranges. The size range of particles
is typically given as a range of particle diameters in nm assuming
spherical shape and must be provided in a comment attribute. Number
concentration means the number of particles or other specified objects
per unit volume. "Aerosol" means the suspended liquid or solid particles
in air (except cloud droplets). "Dry aerosol" means aerosol without water.
particle_surface_area_concentration_of_dry_aerosol_in_air
m-3
Surface area per volume derived from the size resolved particle number
concentration. "Aerosol" means the suspended liquid or solid particles
in air (except cloud droplets). "Dry aerosol" means aerosol without water.
size_resolved_number_concentration_of_cloud_liquid_water_particles_in_air
m-3
Size resolved denotes the capability of an instrument to measure
aerosol properties in different size ranges. The size range of particles
is typically given as a range of particle diameters in nm assuming
spherical shape and must be provided in a comment attribute. Number
concentration means the number of particles or other specified objects
per unit volume. Cloud droplets are spherical and typically a few
micrometers to a few tens of micrometers in diameter. An upper limit of
0.2 mm diameter is sometimes used to distinguish between cloud droplets
and drizzle drops, but in active cumulus clouds strong updrafts can
maintain much larger cloud droplets.
vertical_speed
1
Rate of change of aircraft altitude.
total_air_temperature
K
Total air temperature or stagnation temperature is the temperature at a
stagnation point in a fluid flow. Measured by a temperature probe
mounted on the surface of the aircraft.
I'm not really sure what is the standard procedure. Let me know if you
need any more information.
Best regards,
Damien Boulanger and the IGAS team
