- Purpose
-
Continuous O3 observations at the Nepal Climate Observatory - Pyramid (NCO-P, 5079ma.s.l., Nepal) with the aim of contributing to clarifying the role played by transport processes in determining the O3 levels and variability in one of the world’s most critical high-altitude regions, a
systematic assessment was performed of the influence of SI on O3 concentrations recorded at this GAW-WMO station,
which is considered representative of the Southern Himalayas remote troposphere. As O3 is a powerful greenhouse gases and a dangerous pollutant and due to the increasing emissions of anthropogenic O3 precursors over South Asia, such activity appears to be particularly important also considering that this region is strongly influenced by one of the so-called Atmospheric Brown Clouds, with severe implications on regional climate, air-quality and food security.

The WDCGG employs the following naming scheme.
[Station Code].[Contributor].[Observation Category].[Parameter].[Auxiliary item].[Data type].[Data Version].[Extension]
A file name consists of 10 components, Station Code, Contributor, Observation Category, Parameter, Auxiliary item, Data type, Data version, Update date, and Extension. Each component is delimited with a dot.

The WDCGG encourages Contributors to submit data files that meet the following points. The file format consists of a header part and a data part. Details of the file format are as follows:
1) The data file employs an ASCII format. The WDCGG does NOT accept any files in binary formats including MS-Excel or MS-Word, which could include computer viruses, because of its computer security policy.
2) The header part includes the following 7 items that are necessary to identify the submitted data: CONTRIBUTOR, STATION NAME, PARAMETER, DATA TIME INTERVAL, MEASUREMENT UNIT, MEASUREMENT METHOD, AND STANDARD SCALE.
3) The data part is in a delimiter (such as a space, comma, or tab)-separated format.
4) The data part should, at least, include the date, time, mole fractions, and data flag.
For averaged data, the number of data used to average and the standard deviation are also required. An averaged value and its standard deviation should be derived from the nearest shorter level of the averages, i.e., a monthly mean is derived from daily means, a daily mean from hourly means, and an hourly mean from minutely means. The definition and the meaning of flag should be submitted as metadata .
5) Each data column should be defined according to Tables 7 and 8 in the first line of the data part (i.e., the first line of the data part must be the item names of each data column).
6) DATE is represented in YYYY-MM-DD where YYYY, MM, and DD are year, month, and day respectively. The date for monthly data is represented as the first date of the month; February 2005 is represented as 2005-02-01, for example. DATE points to the beginning of the measurement or average. In the case of irregular measurements (e.g. event sampling), the end date of the measurement is also required. The WDCGG requires the Contributors to employ time representation compliant to ISO 8601.
7) TIME is represented in hh:mm where hh is hour and mm is minute. In the case of a stationary platform, TIME should be local time, and the time difference between local time and universal time is indicated in Time zone in metadata. The 24-hour clock is used. The representation of time for monthly or daily data is 00:00. TIME points to the beginning of the measurement or average. In the case of irregular measurements (e.g. event sampling), the end time of the measurement is also required.
8) In the case that valid values are not obtained, the data part should be filled with non- numbers, characters, or combination thereof, such as “-999” and “NA”, to denote that no values are reported for the field. The field must NOT be left blank.The format of the header part and the order of the data columns are arbitrary.

The measurement mehod used is Light absorption analysis (UV).
The air is sampled by a 1m long intake at 3.5 m height above the ground. The air intake is a inox-steel pipe.
A Teflon sampling line (lenght 1.5m) connects the air intake with the analyser.
