Subject: ENA/C1 - Reprocessed and Corrected: Slightly incorrect location fields
Affected Datastreams: enacsphotaotC1.a1
Description DATA REPROCESSED and CORRECTED: Some of the instruments were being processed with the previous "GRW-Azores" lat/lon/alt instead of the new "ENA-Azores" lat/lon/alt. The differences were minor, but have been corrected. GRW (old) lat = 39.0911 ENA lat = 39.0916 GRW (old) lon = -28.0297 ENA lon = -28.0257 GRW (old) alt = 26 ENA alt = 30.48 The data were archived in October 2016. Please retrieve the reprocessed data for use in your analysis. ORIGINAL DQR CATEGORY: Yellow (suspect) REPROCESSED and CORRECTED DATA ARCHIVED:2016-10 REPROCESS IDENTIFICATION NUMBER: RID 1460 --------------------------------------------------- --- ORIGINAL DQR DESCRIPTION --- --------------------------------------------------- Some of the instruments are being processed with the previous "GRW-Azores" lat/lon/alt instead of the new "ENA-Azores" lat/lon/alt. The differences are minor, but will be corrected. The respective GRW and ENA lat, lon, and alt values are as follows: GRW lat = 39.0911 ; ENA lat = 39.0916 ; GRW lon = -28.0297 ; ENA lon = -28.0257 ; GRW alt = 26 ; ENA alt = 30.48 ;
Measurements
  • lat (North latitude)
  • alt (Altitude above mean sea level)
  • lon (East longitude)

Subject: ENA/MPL/C1 - Higher than expected depolarization ratio
Affected Datastreams: enamplpolfsC1.b1
Description The separation of the two polarized states of the MPL is somewhat deteriorated during the DQR period due to liquid crystal problems. As a result, the depolarization ratio, which is the primary component for identifying liquid water content, is somewhat marginalized. The instrument problem might make the evaluation of liquid clouds less certain.
Measurements
  • signal_return_cross_pol (Attenuated backscatter, cross pol)
  • background_signal_cross_pol (Background signal, cross pol data)
  • background_signal_std_cross_pol (Background signal standard deviation, cross pol data)
