Definition

  • The MODIS Airborne Simulator (MAS) is a modified Daedalus Wildfire scanning spectrometer which flies on a NASA ER-2 aircraft and provides spectral information similar to that which will be provided by the Moderate Resolution Imaging Spectroradiometer (MODIS) scheduled to be launched on the Earth Observing System (EOS)-AM platform in 1998. The principal investigators for MAS are Dr. Michael King (NASA/GSFC) and Dr. Paul Menzel (NOAA/NESDIS). The modified Wildfire instrument was first flown in 1991 in the FIRE Cirrus-II experiment onboard a NASA ER-2 over Kansas and the Gulf coast area. The Wildfire instrument was re-configured to the MAS in 1992 and was flown over the Atlantic Ocean as part of the ASTEX experiment. During 1993, MAS was flown in the southwestern Pacific during TOGA/COARE and CEPEX experiments. In July 1993, MAS was flown over the northeastern United States during the SCAR-A experiment. The MAS is a 50-band spectrometer, but before mid-1994, only 12 bands were used at 8 bit resolution. By October 1999,the MAS was recording information in all 50 visible and infrared spectral bands at 16-bit resolution. From January 1995 to October 1999, the 16 bits resolution was compressed into a 12 bit format. Details of the MAS instrument and data calibration can be found in the MAS level-1B Data User's Guide at http://mas.arc.nasa.gov/reference/guide.html Information about the MAS data and experiments can be found on the MAS Home Page at: http://mas.arc.nasa.gov/ Group: Instrument_Details Entry_ID: MAS Group: Instrument_Identification Instrument_Category: Earth Remote Sensing Instruments Instrument_Class: Passive Remote Sensing Instrument_Type: Spectrometers/Radiometers Instrument_Subtype: Imaging Spectrometers/Radiometers Short_Name: MAS Long_Name: MODIS Airborne Simulator End_Group Group: Associated_Platforms Short_Name: NASA ER-2 End_Group Online_Resource: http://mas.arc.nasa.gov/reference/guide.html Online_Resource: http://mas.arc.nasa.gov/ End_Group (en)
