Hi Jonathan,
This looks fine to me :-).
Best wishes,
Philip

Subject: [CF-metadata] Proposed new standard name:
effective_radius_of_cloud_particle_at_cloud_top
Dear CF board,
Back in May, a colleague of mine, Randy Horne, submitted a new proposed name
for the effective radius of a cloud particle at the top of a cloud. Our
proposed standard name was "effective_radius_of_cloud_particle_at_cloud_top".
We did not hear back from any CF posters at the time in regards to this
proposal, and are hoping to re-start this proposal now.
The motivation for this new standard name is a data product on the future
GOES-R geostationary platform. This product is the effective radius for a
cloud particle at the top of a cloud. The GOES-R product will not distinguish
between water and ice particles, however. Currently, the CF database has a
similar standard name but for liquid particles only
(effective_radius_of_cloud_liquid_water_particle_at_liquid_water_cloud_top).
This standard name does not suffice for the GOES-R data product, hence, the
proposal for a slightly more general standard name which would cover both water
and ice particles at the cloud top. Here is our current proposal:
Standard Name:
effective_radius_of_cloud_particle_at_cloud_top
Definition:
The effective radius of a size distribution of particles, such as aerosols,
cloud droplets or ice crystals, is the area weighted mean radius of particle
size. It is calculated as the ratio of the third to the second moment of the
particle size distribution. cloud_top refers to the top of the highest cloud
and cloud_particle refers to either a liquid water droplet or ice crystal.
Canonical Units:
m
Thanks for your consideration of this proposal. All comments are welcome.
Sincerely,
Jonathan Wrotny
