1 Scope

GB 31224-2014 is the Chinese national standard on specifications for observing environs protection of atmosphere background watch station, in the field of natural and applied sciences. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 30 September 2014 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2015. Classification: ICS 07.060, CCS A47. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the classification of the atmospheric environmental protection zone bottom detection station, and the protection requirements. This standard applies to the atmospheric background stations, as well as protection of the environment to detect other stations having a function of atmospheric background observed.

Appendix A

(Normative) This atmospheric bottom sector division method A.1 Data Requirements A.1.1 site has been built Background stations has been built atmospheric air required sectorized background information comprising. Ground meteorological elements

a) the past three years or more sequences of observations;

b) the past three years or longer sequences atmospheric composition observations;

c) the past three years or other relevant elements longer sequence of observations;

d) air mass after nearly three years or more sequence information to track;

e) the global atmosphere Zhou Bian background station 50.0km geographical range, wherein the underlying surface ecological nature, air pollution, socioeconomic Status and other information. A.1.2 proposed site Atmospheric Atmospheric Background proposed station sectorisation the background information required includes. Ground meteorological elements

a) nearly a year or longer sequence of observations;

b) a composition of the atmosphere in recent years or longer sequences of observations;

c) the past one year or other related elements of a longer sequence of observations;

d) After air mass nearly 1 year or more sequence information to track;

e) the global atmosphere Zhou Bian background station 50.0km geographical range, wherein the underlying surface ecological nature, air pollution, socioeconomic Status and other information. A.2 division method A.2.1 dividing step A.2.1.1 based on surface meteorological observation data elements, making the wind direction frequency of roses, production methods, see A.2.2. A.2.1.2 The observation data relevant atmospheric composition, production of various species direction - concentration roses, production methods, see A.2.3. Wind rose at a frequency graph A.2.1.3, combined with various species direction - the concentration of roses, having a selected high frequency direction, the average concentration of species Lower degree direction, preliminarily determined direction atmospheric background. According to the geographical A.2.1.4, natural ecological characteristics underlying surface, air pollution, socioeconomic status, and other similar air mass trajectory Off secondary observations, the atmospheric verify the orientation. A.2.1.5 bottom of the atmospheric wind direction according to the frequency statistics accumulated in descending order, the cumulative frequency direction and 60% or more The sector is the direction on the bottom of the atmospheric sector. A.2.2 Wind frequency roses A.2.2.1 by North (N), North northeast (NNE), Northeast (NE), East Northeast (ENE), East (E), East Southeast (ESE), Southeast (SE), South Southeast (SSE), south (S), SSW (SSW), Southwest (SW), WSW (WSW), West (W), North West (WNW), northwest (NW) and the North West North (NNW) 16 orientations production Leinian wind direction frequency roses. Each wind A.2.2.2 Leinian frequency, according to equation (A.1) is calculated. F = M × 100% (A.1) Where.

--- F. Leinian a frequency direction; N

--- Leinian a number of wind appears; M

--- For ages total number of each wind direction (including calm winds) occur. Wind A.2.3 - concentration roses A.2.3.1 Press the north (N), North northeast (NNE), Northeast (NE), East Northeast (ENE), East (E), East Southeast (ESE), Southeast (SE), South Southeast (SSE), south (S), SSW (SSW), Southwest (SW), WSW (WSW), West (W), North West (WNW), northwest (NW) and the North West North (NNW) 16 wind azimuth production - the concentration of roses. A.2.3.2 using data produced hour concentration Species concentration histogram on each direction. The average concentration of species highest frequency A.2.3.3 parties appears taken up, making the wind - the concentration of the rose diagram. A.2.4 sectors delineated Atmospheric Background A.2.4.1 determined by the orientation of the atmospheric A.2.1. A.2.4.2 If the angle between the direction of the other end of the atmospheric air present in a direction of the bottom adjacent thereto greater than 45 °, the bottom of the atmospheric direction of the fan Region is in the central direction of the fan-shaped area within ± 11.25 ° range. A.2.4.3 If the angle between the direction of the other end of the atmospheric air present in a direction of the bottom adjacent thereto is equal to or less than 45 °, the bottom of the atmospheric sector It is the maximum angle of two directions atmospheric background centers, extended after 11.25 ° sector area formed outwardly. A.2.4.4 If the two sectors are not adjacent the bottom of the atmospheric, when the central angle between sectors is smaller than 45 °, the two sectors and the bottom of the atmospheric therebetween Sectors should be combined as the bottom of the atmospheric sector. references [1] GB 16297 Air Pollutant Discharge Standard [2] GB 50180-1993 (2002 edition) urban residential area planning and design specifications [3] HJ2.2-2008 Environmental Impact Assessment Guidelines atmosphere [4] WMONo.49.WorldMeteorologicalOrganization, TechnicalRegulationsVolume1, General MeteorologicalStandardsandRecommendedPractices, 1988edition
