Subject:	SBS/MET/M1 - Atmospheric pressure spikes
DataStreams:	sbsmetM1.b1
Description:	A nearby AC unit was causing +/-.05 (approx.) changes in pressure values, most frequently during the daylight hours but occasionally over night. Corrective action was taken to shield the sensor 1/28.
Measurements:	sbsmetM1.b1: Barometric Pressure(atmos_pressure)

Subject:	SBS/MET/M1 - Site setup
DataStreams:	sbsmetM1.b1
Description:	The instruments were being setup and installed during this period. Some data may be questionable and minimal quality reporting will be done.

Subject:	SBS/MET/M1 - Incorrect atmospheric pressure
DataStreams:	sbsmetM1.b1
Description:	The atmospheric pressure readings showed a ~.3 - 1 mb oscillatory behavior. The sensor tube was found to be obstructed. It was fixed and proper function resumed.
Measurements:	sbsmetM1.b1: Barometric Pressure(atmos_pressure)

Subject:	GAN/MET/M1 - Tower lowered and tipped for maintenance
DataStreams:	ganmetM1.b1
Description:	The met tower was lowered for a PIR replacement. All met tower data are questionable during this period.

Subject:	GAN/MET/M1 - Met data questionable
DataStreams:	ganmetM1.b1
Description:	Met data are questionable during this time period as the system was being deployed and in various states of operation.
Measurements:	ganmetM1.b1: lat precip_rate_max precip_rate_min wind_spd_arith_sd time_offset Vector-averaged Wind Speed(wind_spd_vec_avg) lon Rain, surface, 1-min avg(precip_rate_mean) Vapor pressure mean(vappress_mean) precip_rate_sd Relative humidity mean(relh_mean) base_time alt Vector-averaged Wind Direction(wind_dir_vec_avg) Barometric Pressure(atmos_pressure) pwd_err_code Mean Air Temperature or Hardware Error(temp_mean) pwd_pw_code_inst pwd_pw_code_1_hr logger_voltage pwd_cumul_water time wind_dir_sd wind_spd_arith_max vappress_sd Average 10 min visibility(pwd_avg_vis_10_min) pwd_avg_H2O_int_1_min wind_spd_arith_min pwd_cumul_snow pwd_pw_code_15_min pwd_id Wind speed, lower, 1-min avg(wind_spd_arith_avg) logger_temp Average 1 min visibility(pwd_avg_vis_1_min) temp_sd org_carrier_mean relh_sd

Subject:	GAN/MET/M1 - Intermittent PWD alarm
DataStreams:	ganmetM1.b1
Description:	Intermittent backscatter alarms were tripping on the PWD suggesting something was blocking (dew) or getting into the measurement path (spider or ants). Problem resolved 10/9 with no clear indication of the cause.
Measurements:	ganmetM1.b1: pwd_pw_code_15_min pwd_id pwd_pw_code_inst pwd_pw_code_1_hr pwd_cumul_water Average 1 min visibility(pwd_avg_vis_1_min) Average 10 min visibility(pwd_avg_vis_10_min) pwd_avg_H2O_int_1_min pwd_cumul_snow pwd_err_code
