MODIS Reflective Band Specifications

MODIS Emissive Band Specifications

AIRS Instrument Suite•AIRS, in conjunction with its companion instrument AMSU, provides a unprecedented suite of instruments for weather and climatologically studies

– AIRS is a hyperspectral IR spectral photometer • 2378 IR channels• AIRS also has 4 Visible/NIR channels (8x9 pixels per AIRS spot)

– AMSU-A is a MW temperature sounder with 15 channels– Combining Level-1B data from AIRS-suite instruments you can

retrieve cloud-cleared IR radiances and physical parameters including:

• Cloud cover & height• Surface temperature & type• Profiles of: T, q, trace gasses

Climate Studies

• EOS Satellites primary mission is to understand earth’s climate and identify the causes of climate change.

• DAAC products are doing just that.

Near Real-time Data and Products

• Direct readout Terra and Aqua data and products have proven useful too.

• IMAPP (International MODIS/AIRS Processing Package) allows users with X-band receivers to calibrate, geolocate and create science data products in near-real time.

• Current suite: MODIS data Calibration, geolocation, cloud mask, cloud properties (height, temperature, emissivity, phase), atmospheric profiles (T, q, total precipitable water vapor, stability indices.)

EOS Direct Broadcast at SSEC

Objective: Routine acquisition and processing of EOS direct broadcast data (NASA HQ funding).

Accomplishments:

• System installed August 5, 2000.

• Level-1B data and browse images have been produced automatically since January, 2001 and made available via anonymous FTP, DODS server, and Web.

• IMAPP software package for processing MODIS direct broadcast data now in use in USA, UK, Germany, Russia, Japan, China, Korea, Singapore, Australia. Level-2 algorithms (cloud mask, atm. profiles, cloud height).

EOS Direct Broadcast Groundstation

International MODIS/AIRS Processing Package

Goal: Transform direct broadcast Level-0 data (initially from MODIS) to calibrated & geolocated radiances (Level-1B) and science data products (Level-2).

Features:• Ported to a range of platforms (IRIX, SunOS, AIX, HPUX, Linux),• The only required tool kit is NCSA HDF4,• Processing environment is greatly simplified,• Downlinked or definitive ephemeris/attitude data may be used,• Passes of arbitrary size may be processed,• Available at no cost; licensed under GNU GPL,
