Subject:	SGP/MPL/C1 - Reduced detection sensitivity
DataStreams:	sgpmplC1.a1, sgpmplcmask1clothC1.c1, sgpmplnor1campC1.c1, sgpmplsmask1clothC1.c1
Description:	During the time periods indicated, the laser power supply was low. This resulted in compromised detection sensitivity, particularly for thin clouds and/or during daylight hours. That is, some clouds may not have been identified. The low laser power would not have resulted in false positives.
Measurements:	sgpmplC1.a1: Preliminary cloud base height above ground level(preliminary_cbh) sgpmplnor1campC1.c1: Cloud base height(cloud_base_height) cloud_mask_2 cloud_mask_1 Cloud top height(cloud_top_height) cloud_top_attenuation_flag sgpmplsmask1clothC1.c1: MPL Cloth et al. Algorithm Significance Mask(SigniMaskMplCloth) sgpmplcmask1clothC1.c1: MPL Cloth et al. Algorithm Cloud Mask(CloudMaskMplCloth)

Subject:	SGP/MPL/C1 - Instrument offline
DataStreams:	sgpmplC1.a1, sgpmplcmask1clothC1.c1, sgpmplnor1campC1.c1, sgpmplsmask1clothC1.c1
Description:	Instrument was taken offline due to a failure of the laser power supply. Data are missing and unrecoverable.
