Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 19117-2003 "acid rain observation specification", compared with GB/T 19117-2003 main technical changes are as follows.
- modified the definition of "pH for atmospheric precipitation" (see 3.3, 3.3 of.2003);
- the definition of "atmospheric precipitation conductivity" (see 3.4,.2003 3.4);
- the definition of "standard buffer solution" has been added (see 3.5);
- Increased technical requirements for automatic precipitation sampling equipment (see 6.2);
- Increased technical requirements for periodic verification of pH and conductivity meters (see 8.3);
- Increased technical specifications for the performance of the electrode for measuring electrode performance and conductivity (see 8.1 and 8.2);
- technical provisions for the verification of precipitation pH and precipitation conductance data (see 11.1 and Appendix D);
- modified the style of the acid rain observation record book in Appendix F (informative) (see Appendix F, Edition.2003)
Appendix E);
- Added technical requirements for the format of the observational data document (see Appendix G) in Appendix G (informative);
- amended the technical requirements for the recording of relevant weather phenomena in Appendix H (informative) (see Appendix H, Edition.2003)
Appendix F).
This standard is proposed by the China Meteorological Administration.
This standard by the National Climate and Climate Change Standardization Technical Committee of Atmospheric Component Observation and Forecasting Service Subcommittee
(SAC/TC540/SC1).

3 terms and definitions
The following terms and definitions apply to this document.
3.1
Acid rain acidrain
pH precipitation is less than 5.60.
Note. Precipitation forms include liquid precipitation, solid precipitation and mixed precipitation.
3.2
Acid rain observation
Collecting precipitation samples systematically at fixed site sites, measuring atmospheric pH and atmospheric precipitation conductivity, providing chemical
Analysis of precipitation samples.
3.3
PH value of atmospheric precipitation pHvalueofprecipitation
Negative logarithm of hydrogen ion activity in atmospheric precipitation.
pH = -lg [H]
Where.
pH --- atmospheric precipitation pH, dimensionless;
[H] - Hydrogen ion activity in moles per liter (mol·L-1).
3.4
Precipitation Conductivity of the Precipitation
The measurement of the conductivity of atmospheric precipitation is measured by the current density of the atmospheric precipitation sample in the conductivity measurement cell and the intensity of the electric field applied thereto
Ratio.
