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 base_time Relative humidity mean(relh_mean) 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 logger_voltage pwd_cumul_water pwd_pw_code_1_hr time wind_dir_sd wind_spd_arith_max vappress_sd Average 10 min visibility(pwd_avg_vis_10_min) wind_spd_arith_min pwd_avg_H2O_int_1_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_err_code pwd_cumul_snow

Subject:	GAN/RAIN/M1 - Incorrect precipitation data
DataStreams:	ganrainM1.b1
Description:	The weighing bucket rain gauge was not reporting rainfall when other sensors were reporting rainfall, possibly due to configuration or connection problems.

Subject:	GAN/RAIN/M1 - Precipitation not measured
DataStreams:	ganrainM1.b1
Description:	After maintenance and emptying of the bucket, the data flat-lined at zero due to communications problems.

Subject:	GAN/RAIN/M1 - Noise in sensor 3
DataStreams:	ganrainM1.b1
Description:	Sensor 3 was noisy after data collection resumed. This noise cleared up on its own by 20111212 123000 and the noise will only effect the raw data. The ingest which produces the b1 version of the data removes the noise.
Measurements:	ganrainM1.b1: frequency3 total_weight Precipitation rate(precip_rate) Precipitation, total(precip) weight3
