Data Product Description |
MOD04_L2
MODIS/Terra Aerosol 5-Min L2 Swath 10km
|
The MODIS Level 2 aerosol product, MOD04_L2, provides retrieved ambient
aerosol optical properties (e.g., optical thickness and size
distribution), mass concentration, look-up table derived reflected and
transmitted fluxes, as well as quality assurance and other ancillary
parameters, globally over ocean and near globally over land at a spatial
resolution of 10 km at nadir.
|
MOD05_L2
MODIS/Terra Total Precipitable Water Vapor 5-Min L2 Swath 1km and 5km
|
This Level 2 data collection contains derived precipitable column water
vapor amounts, during daytime using a near-infrared over clear land
areas and above clouds over both land and ocean; water vapor estimates
are provided over clear ocean areas.
|
MOD06_L2
MODIS/Terra Clouds 5-Min L2 Swath 1km and 5km
|
The Level 2 MODIS atmospheric cloud product, MOD06_L2, consists of cloud
top physical parameters (temperature, pressure, effective emissivity),
cloud phase, cloud optical parameters (optical depth, effective particle
radius, water path), cirrus reflectance in the visible band, contrail
flag, and other derived parameters over the globe at spatial resolution
of 1 km or 5 km at nadir. This product consists of 46 parameters.
|
MOD07_L2
MODIS/Terra Temperature and Water Vapor Profiles 5-Min L2 Swath 5km
|
The MODIS Atmospheric Profile data product file MOD07_L2 onsists of
several parameters: they are total-ozone burden, atmospheric stability,
temperature and moisture profiles, and atmospheric water vapor. All of
these parameters are produced day and night for Level 2 at 5x5 1-km
pixel resolution when at least 9 FOVs are cloud free. The MODIS
total-ozone burden is an estimate of the total-column tropospheric and
stratospheric ozone content. The MODIS atmospheric stability consists
of three daily Level 2 atmospheric stability indices. The Total Totals
(TT), the Lifted Index (LI), and the K index (K) are each computed using
the infrared temperature- and moisture-profile data, also derived as
part of MOD07. The MODIS temperature and moisture profiles are produced
at 20 vertical levels. The MODIS atmospheric water-vapor product is an
estimate of the total tropospheric column water vapor made from
integrated MODIS infrared retrievals of atmospheric moisture profiles in
clear scenes.
|
MOD35_L2
MODIS/Terra Cloud Mask and Spectral Test Results 5-Min L2 Swath 250m and 1km
|
The Level 2 MODIS cloud mask product, MOD35_L2, consists of global cloud
mask, quality assurance, and other ancillary parameters. The visible
and infrared threshold and consistency tests are used to specify
confidence levels that an unobstructed view of the Earth's surface is
observed. An indication of shadows affecting the scene is also
provided. MOD35_L2 parameters are produced at spatial resolution of
1-km and 250-m at nadir. Including ancillary parameters, this product
consists of 9 parameters.
|
MODATML2
MODIS/Terra Joint (Cloud, Aerosol, Water Vapor and Profile) 5-Min L2 Swath at 5-km and 10-km
|
MODATML2 contains a combination of key high interest science parameters
obtained from the complete set of standard at-launch Level-2 Source
Products: Aerosol Properties (Optical Depth, Small Mode Optical Depth
Ratio, Small and Large Mode Solution Index over Ocean, Effective
Particle Radius and QA Flags), Water Vapor Properties (Near-IR and IR
Total Column Water), Cloud Properties (Optical Thickness, Effective
Radius, Phase, Cloud Top Temperature and Pressure, Cloud Fraction and
Cirrus Reflectance) and Cloud Mask Flags. It is to be noted that two
sets of geolocation arrays (5 km and 10 km resolution) are provided in
this product. Some of the science parameters (cloud, water-vapor and
cloud mask) have been subsampled to 5 km, from the original 1 km data.
This product was designed to be compact (a single CD can contain one
full day of data files!) yet robust enough to be useful to a significant
number of MODIS data users.
