The KMZ files contain data extracted from the CALIPSO’s Lidar Level 1 Expedited data granules Versions 3.40 or 3.30.
The data parameter the KMZ files contain is the Total_Attenuated_Backscatter_532. For more information
on this data parameter, refer to the
CALIPSO User’s Guide.

Lidar Level 1 Version 3.30 Quality Summary.
Standard Data Set Definition:
Standard data processing begins immediately upon delivery of all required ancillary data sets.
The ancillary data sets used in standard processing (e.g., GMAO meteorological data and
data from the National Snow and Ice Data Center) must be spatially and temporally
matched to the CALIPSO data acquisition times, and thus the time lag latency between data
onboard acquisition and the start of standard processing can be on the order of several days.
The data in each data set are global, but are produced in files by half orbit, with the day
portion of an orbit in one file and the night portion of the orbit in another.
Expedited Data Set Definition:
Expedited data are processed as soon as possible after following downlink from the satellite
and delivery to LaRC. Latency between onboard acquisition and analysis expedited processing
is typically on the order of 6 to 28 hours. Expedited processing uses the most recently
current available set of ancillary data (e.g., GMAO meteorological profiles) and calibration
coefficients available, which may lag the CALIPSO data acquisition time/date by several days.
Expedited data files contain at the most, 90 minutes of data. Therefore, each file may contain
both day and night data.
Users are strongly cautioned against using Expedited data products as
the basis for research findings or journal publications. Standard data sets only should be used
for these purposes.
