The measured parameter is Particle number concentrations units of #/cm3 per size bin, range size= 0.25 ...30 µm in 31 channels. 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.

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. true MEASURED PARAMETER: Particle number concentrations units of #/cm3 per size bin COVERING PERIOD:March2006-December 2006 UNIT:#/cm3 (number/cubiccentimeter) INSTRUMENT: Optical Particle Counter - Dust Monitor 190 GRIMM TIME INTERVAL:continuos CALIBRATION :by factory TIME RESOLUTION: "30-min," averaged between minutes: 00-29 and 30-59 Size resolution: 31 channels, counts Concentration range: 0.1 to 1500 µg/m³ Size range: 0.25 ...30 µm in 31 channels Sample: intake flow rate 1.2 l/min File Name of Archived Data File Name of Archived Data File Name of Archived Data The WDCGG employs the following naming scheme: [Station code].[Contributor].[Observation category].[Sampling type].
