Description of wet deposition monitoring data

The csv file from 2000 to 2009 data consists of the following 6 components.
・Form(Wet A) No.1＜From column B to AB＞  …… Results of wet deposition analysis (Anion)
・Form(Wet A) No.2＜From column AD to BH＞ …… Results of wet deposition analysis (Cation)
・Form(Wet A) No.3＜From column BJ to CO＞ …… Results of wet deposition analysis (EC, pH, R1, R2 and Precipitation)
・Summary1 ＜From column CQ to DD＞    ………… Results of wet deposition analysis including non-sea-salt sulfate and non-sea-salt calcium
・Summary2 ＜From column DF to DU＞    ………… Calculation results of wet deposition amount
・Summary3 ＜From column DW to ET＞    ………… Calculation results of equivalent concentration, R1, conductivity and R2

The csv file after 2010 data consists of the following 8 components.
・Form(Wet A) No.1＜From column B to AV＞  …… Results of wet deposition analysis (Anion)
・Form(Wet A) No.2＜From column AX to CF＞ …… Results of wet deposition analysis (Cation)
・Form(Wet A) No.3＜From column CH to DM＞ …… Results of wet deposition analysis (EC, pH, R1, R2 and Precipitation)
・Form(Wet A) No.4＜From column DO to EN＞ …… Results of wet deposition analysis (Organic ions)
・Summary1 ＜From column EQ to EZ＞ ………… Calculation results of non-sea-salt sulfate, non-sea-salt calcium and organic ions considering the dissociation constant
・Summary2 ＜From column FB to GE＞ ………… Calculation results of wet deposition amount
・Summary3 ＜From column GG to HI＞ ………… Calculation results of equivalent concentration and R1
・Summary4 ＜From column HK to IR＞ ………… Calculation results of conductivity and R2

*As for Form (Wet A), the cell of the analytical result is blank in case that the analysis is not conducted.
 And the following flags are used in Form (Wet A).

Flags:
999  Missing measurement, reason not specified.
899  Measurement not defined, reason not specified.
783  Low precipitation, concentration unknown.
782  Low precipitation value is obtained from diluted sample
781  Below detection limit.
701  Less accurate than usual, reason not specified.
699  Mechanical problem, reason not specified.
599  Contamination not specified.
478  Inconsistency discovered through ion balance calculation.
477  Inconsistency between measured and estimated electric conductivity.

*The data of annual values (total amount, mean value, minimum and maximum value) are included in summary 2, 3 and 4.

*R1: Ion balance between cations and anions, R2: Electrical conductivity balance between measured and calculated values.

* The monitoring data from 2000 to 2009 data are different from the data after 2010 in the calculation method of R1 and R2.
When pH is greater than 6, hydrogen carbonate (HCO3-) concentration is included for the computation of R1 and R2. 
HCO3- concentration is calculated from the dissociation constant (Ka) and pH.
(In the case that HCO3- concentration is measured, the analysis result is considered in the evaluation of R1 and R2.) 
Air concetration of CO2 in equilibrium with precipitation samples is assumed to be 360 ppm. 
Dissociation constant in terms of pKa for carbonic acid is 6.35.
