This Level 1B collection contains MODIS On-Board Calibrator and Engineering Data.
MYD03
MODIS/Aqua Geolocation Fields 5-Min L1A Swath 1km
Geolocation collection contains geodetic latitude and longitude, surface height above geoid, solar zenith and azimuth angles, satellite zenith and azimuth angles, and a land/sea mask for each 1km sample.

MODIS/Aqua Atmosphere Products

MODIS/Aqua Data Product Data Product Description
MYD04_L2
MODIS/Aqua Aerosol 5-Min L2 Swath 10km
The MODIS Level 2 aerosol product, MYD04_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.
MYD05_L2
MODIS/Aqua 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.
MYD06_L2
MODIS/Aqua Clouds 5-Min L2 Swath 1km and 5km
The Level 2 MODIS atmospheric cloud product, MYD06_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.
MYD07_L2
MODIS/Aqua Temperature and Water Vapor Profiles 5-Min L2 Swath 5km
The MODIS Atmospheric Profile data product file MYD07_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 MYD07. 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.
MYD35_L2
MODIS/Aqua Cloud Mask and Spectral Test Results 5-Min L2 Swath 250m and 1km
The Level 2 MODIS cloud mask product, MYD35_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. MYD35_L2 parameters are produced at spatial resolution of 1-km and 250-m at nadir. Including ancillary parameters, this product consists of 9 parameters.
MYDATML2
MODIS/Aqua Joint (Cloud, Aerosol, Water Vapor and Profile) 5-Min L2 Swath at 5-km and 10-km
MYDATML2 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.
MYD08_D3
MODIS/Aqua Aerosol Cloud Water Vapor Ozone Daily L3 Global 1Deg CMG
This is a level-3 MODIS gridded atmosphere daily global joint product, MYD08_D3. It contains daily 1 x 1 degree grid average values of atmospheric parameters related to atmospheric aerosol particle properties, total ozone burden, atmospheric water vapor, cloud optical and physical properties, and atmospheric stability indices.
MYD08_E3
