This is the wide-swath MODIS/Aqua subset along CloudSat field of view track.
The goal of the wide-swath subset is to select and return MODIS data that are
within +-100 km across the CloudSat track. I.e. the resultant MODIS subset
swath is sought to be about 200 km cross-track. However, the original MYD06_L2
has data of 5- and 1-km pixels. Thus, MAC06S1 cross-track width is 41- and
201-pixels, ... depending on the parameter.Along-track, all MODIS pixels from the
original product are preserved.
In the standard product, the level-2 MODIS cloud product consists of cloud
optical and physical parameters. These parameters are derived using remotely
sensed infrared, visible and near infrared solar reflected radiances. MODIS
infrared channel radiances are used to derive cloud top temperature, cloud top
height, effective emissivity, cloud phase (ice vs. water, opaque vs.
non-opaque), and cloud fraction under both daytime and nighttime conditions.
MODIS visible radiances are used to derive cloud optical thickness and
effective particle radius and cloud shadow effects. Near infrared solar
reflected radiance provides additional information in the retrieval of cloud
particle phase (ice vs. water, clouds vs. snow). The shortname for this level-2
MODIS cloud product is MYD06_L2 and the principal investigators for this
product are MODIS scientists Dr. Bo-Cai Gao (email@example.com) for cirrus
cloud detection; Dr. Paul Menzel (firstname.lastname@example.org) for cloud top
properties; and Dr. Michael King(email@example.com) for cloud optical
"Two day repeat observations with a repeat orbit pattern every 16 days. The
locales where the ascending and descending modes are close or intersect can
have two observations per day."
(The shortname for this product is MAC06S1).
