Many oper… Slawomir Blonski, Frank Padula, Xi Shao and Yan Bai . In this section you can peruse the collected presentations, meeting minutes and agendas of previous meetings. The MODIS Science Team Meeting is held once a year in combination with the VIIRS Science Team, so that the members of these science teams may assemble and discuss data they have collected, ideas they have formed, and future issues that apply to the MODIS and VIIRS instruments. Data are available to the user through an interactive web page.

It is expected that this redundancy will reduce system downtime to less than 1%. With contributions from . The VIIRS aerosol optical thickness (AOT) at 550 nm EDR at current Provisional maturity level is evaluated by comparing it with MODIS retrievals and measurements from the Aerosol Robotic Network (AERONET).

These products are being used by scientists from a variety of disciplines, including oceanography, biology, and atmospheric science. “There are many standard MODIS data products that scientists are using to study global change. This section provides some detail for each product individually, introducing you to the products, explaining the science behind them, and alerting you […] Active Fire Data Download active fire products from the MODIS and VIIRS for the last 24, 48 hours and 7 days in shapefile, KML, WMS or text file formats. The agreement between the generated AST product and the validation data sets over the more than 5000 locations suggested that the VIIRS AST product is compatible with the heritage MODIS land cover product (C5.0), and the classification accuracy meets the L1RD requirements. The VIIRS sensor was designed to extend and improve upon the series of measurements initiated by its predecessors, the Advanced Very High Resolution Radiometer (AVHRR), the Moderate Resolution Imaging Spectroradiometer (MODIS), and the Sea-viewing Wide Field-of-view Sensor (SeaWIFS). VIIRS and MODIS Intercomparison Results Sirish Uprety and Changyong Cao . For more … The user specifies data product of interest and the area of interest by entering geographic coordinates or selecting the location on a map. MODIS and VIIRS Land Products Global Subsetting and Visualization Tool. While the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor, aboard the Suomi-NPP satellite, and Aqua have similar orbital characteristics and compatible sampling of the diurnal cycle of fire activity, sensor differences, including pixel sizes, along-scan aggregation, and swath width result in inherent differences in the expected fire observations. The VIIRS aerosol optical thickness (AOT) at 550 nm EDR at current Provisional maturity level is evaluated by comparing it with MODIS retrievals and measurements from the Aerosol Robotic Network (AERONET).

The following tables list all Collection 6 (C6), Collection 6.1 (C6.1) MODIS, Collection 1 (C1) SNPP VIIRS, and Collection 2 (C2) JPSS1 VIIRS products produced by LANCE-MODIS. These products are being used by scientists from a variety of disciplines, including oceanography, biology, and atmospheric science. As more VIIRS data are validated and processed, the NSIDC DAAC will archive and distribute a range of VIIRS products that echo the current strategy applied to MODIS. Slawomir Blonski, Frank Padula, Xi Shao and Yan Bai . Compared to 2014 (left), the extent and depth of the snowpack along the Sierra Nevada Mountains in California decreased in 2015 (right). ORNL DAAC: The MODIS/VIIRS Global Subsetting and Visualization Tool provides on-demand, customized subsets of several MODIS Collection 6 and VIIRS (Version 001) land products. Tables provide links to the download site for each product and to browse data, if available. “There are many standard MODIS data products that scientists are using to study global change. Level 0-3 Near real-time (NRT) products are provided from the MODIS (Moderate Resolution Imaging Spectroradiometer) instruments on both the Terra (AM) and Aqua (PM) satellites. Both the LANCE-MODIS and LANCE VIIRS-Land elements are provided by the MODIS Adaptive Processing System (MODAPS) operated by the GSFC Terrestrial Information Systems Laboratory, Code 619. LANCE MODIS and VIIRS Near Real Time (NRT) production operates 24 hours a day, 7 days a week, using two standalone systems on separate network routes. Subset obtained for MOD13Q1 product at 35.9587N,84.2874W, time period: 2000-02-18 to 2018-02-18, and subset size: 100.25 x 100.25 km. Satellite remote sensing data are critical for assessing ecosystem state and evaluating long-term trends and shifts in ecosystem components. Accessed March 28, 2018.
