Definition

  • The Moderate Resolution Imaging Spectroradiometer (MODIS) is a multi-disciplinary, keystone instrument on Aqua and Terra, providing a wide array of multispectral, daily observations of land, ocean, and atmosphere features at spatial resolutions between 250 m and 1000 m. Approximately 40 data products are produced from the MODIS data. Data are distributed not only through the EOS Data and Information Service (EOSDIS) Distributed Active Archive Centers (DAACs) at Goddard Space Flight Center, the EROS Data Center in Sioux Falls, South Dakota, and the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado, but also via over 100 Direct Broadcast (DB) stations distributed world-wide. Key MODIS Facts Heritage: AVHRR, HIRS, Landsat TM, and Nimbus-7 CZCS Instrument Type: Medium-resolution, multi-spectral, cross-track scanning radiometer; daylight reflection and day/night emission spectral imaging Swath Width: 2,300 km at 110 degree (&#177;55 degree) Coverage: Global coverage every 1 to 2 days Spatial Resolution: 250 m, 500 m, 1 km Dimensions: 1.04 m x 1.18 m x 1.63 m Mass: 229 kg Thermal Operating Range: 268 &#177; 5 K Power: 162.5 W (average), 225 W (peak) Duty Cycle: 100% Instrument Nadir IFOV: 250 m (2 bands), 500 m (5 bands), 1,000 m (29 bands) Polarization Sensitivity: 2% from 0.43 &#181;m to 2.2 &#181;m and &#177;45 degree scan Signal-to-Noise Ratios: From 500 to 1100 for 1-km ocean color bands at 70 degree solar zenith angle NEDt: Typically < 0.05 K at 300 K Absolute Irradiance Accuracy: 5% for wavelengths < 3 &#181;m and 1% for wavelengths > 3 &#181;m Group: Instrument_Details Entry_ID: MODIS 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: MODIS Long_Name: Moderate-Resolution Imaging Spectroradiometer End_Group Group: Associated_Platforms Short_Name: TERRA Short_Name: AQUA End_Group Group: Spectral_Frequency_Information Wavelength_Keyword: Visible Number_Channels: 10 Channels Spectral_Frequency_Coverage_Range: 0.4 - 0.7 &#181;m End_Group Group: Spectral_Frequency_Information Wavelength_Keyword: Infrared > Reflected Number_Channels: 10 Channels Spectral_Frequency_Coverage_Range: 0.75 - 3 &#181;m End_Group Group: Spectral_Frequency_Information Wavelength_Keyword: Infrared > Thermal Number_Channels: 16 Channels Spectral_Frequency_Coverage_Range: 3.0 - 14.5 &#181;m End_Group Online_Resource: https://modis.gsfc.nasa.gov/ Online_Resource: https://modis-land.gsfc.nasa.gov/ Online_Resource: https://lpdaac.usgs.gov/dataset_discovery/modis/modis_products_table Online_Resource: https://atmosphere-imager.gsfc.nasa.gov/ Online_Resource: https://nsidc.org/data/modis/index.html Online_Resource: https://ladsweb.modaps.eosdis.nasa.gov/ Online_Resource: https://oceancolor.gsfc.nasa.gov Online_Resource: https://mcst.gsfc.nasa.gov/ Online_Resource: https://modis.gsfc.nasa.gov/data/ Online_Resource: https://modis.gsfc.nasa.gov/data/dataprod/index.php Sample_Image: httpa://modis.gsfc.nasa.gov/about/images/modisComponents.jpg Creation_Date: 2007-04-16 Group: Instrument_Logistics Data_Rate: 6.2Mbps (average), 10.5 Mbps (daytime), 3.2 Mbps (nighttime) Instrument_Start_Date: 2002-06-25 Instrument_Owner: USA/NASA End_Group Group: Instrument_Logistics Data_Rate: 6.2Mbps (average), 10.5 Mbps (daytime), 3.2 Mbps (nighttime) Instrument_Start_Date: 2000-02-24 Instrument_Owner: USA/NASA End_Group End_Group (en)
