- Purpose
- Since March 2006, continuous measurements particles number have been carried out. The study is carried out within the framework of the Ev-K2-CNR “SHARE-Asia” (Stations at High Altitude for Research on the Environment in Asia) and UNEP—“ABC” (Atmospheric Brown Clouds) projects. With the name of “Nepal Climate Observatory—Pyramid” the station is now part of the Observatory program of the ABC project.

- Explanation
-
The time resolution of the CN record should allow generation of hourly statistics, preferably
from integrals taken over 1 to 3 minute periods. These should include arithmetic mean and
standard deviation, median, 5%ile and 95%ile CN concentration for each hour. Quality control of
data is the responsibility of each observing station, data known to be contaminated or otherwise
corrupted should be flagged.

The WDCGG employs the following naming scheme:
[Station code].[Contributor].[Observation category].[Sampling type].
[Parameter].[Auxiliary item].[Data type].[Data version]. [Update date].dat
A file name consists of 10 components: Station code, Contributor, Observation category, Sampling type, Parameter, Auxiliary item, Data type, Data version, Update date, and dat.
Each component is delimited with a dot. Below is an example of a file name.
