IMPROVE format. Example records for this file are listed in Table G-25. When background extinction<br />

method number 5 is selected in the control file (MVISBK = 5), nephelometer measurements must be<br />

provided in the IMPROVE format. Example records for this file are listed in Table G-26.<br />

CALPOST uses the content of one field in the file header record to identify which type of file is provided<br />

(it must be consistent with the MVISBK selection). The first 26 characters are read, <strong>and</strong> the characters in<br />

position 24-26 must be >INS= for the nephelometer data file. Subsequent data records are read using the<br />

following statements, where the variable Ameas@ is the extinction coefficient (Mm -1 ):<br />

If similar measurements are available from other sources, they may be used in CALPOST by adhering to<br />

this file structure. Note that the transmissometer measurements are assumed to provide the total<br />

extinction coefficient, whereas the nephelometer measurements provide just the extinction coefficient due<br />

to particle scattering.<br />
