PGD 21

NATIONAL FOREWORD

This Indian Standard which is identical to ISO 19289 : 2015 'Air quality - Meteorology - Siting classifications for surface observing stations on land' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Meteorological Instruments Sectional Committee and after the approval of the Production and General Engineering Division Council.

This standard delineates the guidelines for choosing the site for installing the meteorological instrument that measures the environmental conditions. A careful analysis of the site environmental conditions is to be associated with the knowledge of the instrument characteristics to avoid quantities of influence to distort measurement results affecting their representatives, particularly when a site is supposed to be a representative of a large area (that is, 100 km2 to 1 000 km2).

The text of ISO standard has been approved as suitable for publication as Indian Standard without deviation. Certain conventions are however not identical to those used in the Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and

b) Comma (,) has been used as decimal marker while in Indian Standards it is current practice to use a full point (.) as the decimal marker.
