Subject:	ASI/MWR/M1 - Uncertain calibration-RECALIBRATE
DataStreams:	asimwrlosM1.b1
Description:	There may be a slight obstruction on the radiometer FOV while scanning. The scanning angles were changed.

Subject:	ASI/MPL/M1 - instrument
DataStreams:	asimplpolfsM1.b1
Description:	Later than planned deployment of the instrument.
Measurements:	asimplpolfsM1.b1: scope_temp Preliminary cloud base height(preliminary_cbh) East longitude(lon) qc_scope_temp Pressure, associated geometric height, at altitude, NGM model output(height) num_bins range_bins Attenuated backscatter, cross pol(signal_return_cross_pol) qc_preliminary_cbh polarization_control_voltage Altitude above mean sea level(alt) background_signal_cross_pol Attenuated backscatter, copol(signal_return_co_pol) range_bin_time num_channels energy_monitor North latitude(lat) qc_laser_temp range_bin_width laser_temp background_signal_co_pol qc_detector_temp range_offset polarization_control deadtime_correction time shots_per_avg background_signal_std_co_pol qc_time overlap_correction_heights dead_time_corrected deadtime_correction_counts qc_energy_monitor max_altitude laser_fire_bin background_signal_std_cross_pol overlap_correction detector_temp qc_signal_return_co_pol range pulse_rep qc_signal_return_cross_pol base_time mcs_mode first_data_bin time_offset qc_range_offset

Subject:	ASI/CEIL/M1 - data communication
DataStreams:	asiceilM1.b1
Description:	The data were intermittent, especially on 7/19/2016, due to poor serial communication. The cable was repaired on 7/21 and the serial device server and instrument were power-cycled on 7/28.
Measurements:	asiceilM1.b1: alt_highest_signal range_bounds tilt_angle Third cloud base height(third_cbh) measurement_parameters range window_transmission status_flag sum_backscatter Cloud, base height, lowest base sensed(first_cbh) laser_temperature Backscatter, ceilometer, range and sensitivity corrected(backscatter) background_light laser_pulse_energy Cloud, base height, second lowest base sensed(second_cbh) vertical_visibility status_string detection_status

Subject:	ASI/MPL/M1 - Instrument, Processing
DataStreams:	asimplpolfsM1.b1
Description:	To understand what was causing frequent spikes in the MPL energy levels, the averaging time was increased to 30s. This was reverted back to the original 10s averaging time at the end of the DQR period.

Subject:	ASI/KASACR/M1 - Incorrect velocity sign
DataStreams:	asikasacrppiM1.a1, asikasacrblrhiM1.a1, asikasacrvptM1.a1
Description:	The mean Doppler velocity has the incorrect sign.
Measurements:	asikasacrppiM1.a1: Mean Doppler Velocity(mean_doppler_velocity) asikasacrvptM1.a1: Mean Doppler Velocity(mean_doppler_velocity) asikasacrblrhiM1.a1: Mean Doppler Velocity(mean_doppler_velocity)
