Measurement cycle is 20 seconds on, 5 seconds off at approximately 1 Hz. UNCERTAINTY: estimate of NO2 calibration bottle accuracy is +/-5 percent ULOD_FLAG: 7777777 ULOD_VALUE: N/A LLOD_FLAG: 8888888 LLOD_VALUE: N/A; N/A; N/A; N/A; N/A; DM_CONTACT_INFO: Paul Wooldridge, UC Berkeley, pjwool@berkeley.edu PROJECT_INFO: TC4; 13 July - 13 August 2007 STIPULATIONS_ON_USE: Use of these data requires PRIOR OK from the PI OTHER_COMMENTS: N/A REVISION: R2 R2: ULOD and LLOD flags changed to positive values, to conform to Ames format 2.1 specifications. R1: Corrected for quenching of NO2 fluoresence by H2O using DLH data, further chemical corrections pending. start_UTC stop_UTC mid_UTC NO2 NO2_sigma PNs PNs_sigma 46648 46658 46653 999999 999999 999999 999999
