These data are termed Derived since they use a combination of gauges to best estimate the atmospheric pressure.  The variable \"baromSource\" indicates which instrument was used\n  baromSource == 1 was a Yellow Springs Instruments (YSI) pressure transducer (FRF gauge ID 616)\' LF]; \n  baromSource == 1 was a Paroscientific Digiquartz (model 216B-101) barometer (FRF gauge ID 626)\' LF];\n  baromSource = 0 for interpolated data - maximum of 6 hours\' LF];\nData were typically sampled at 2 Hz and mean values are computed at 10 minute intervals. Approximate location of the gauges is 36.18213 Deg N, 75.75131 W, 9m elevation (NAVD88).\n";
