The MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG (MOD10C1) data set contains snow cover and Quality Assessment (QA) data, latitudes and longitudes in compressed Hierarchical Data Format-Earth Observing System (HDF-EOS) format, and corresponding metadata. 2021-04-12 · The MODIS instrument aboard the Terra satellite experienced a Printed Wire Assembly (PWA) failure on 5 October 2020. This resulted in a reduction in the overall Terra daytime coverage and many of the MODIS/Terra imagery layers have a slightly jagged appearance with less coverage over the northern high latitude regions. The Moderate Resolution Imaging Spectroradiometer (MODIS) is a payload imaging sensor built by Santa Barbara Remote Sensing that was launched into Earth orbit by NASA in 1999 on board the Terra (EOS AM) satellite, and in 2002 on board the Aqua (EOS PM) satellite.

The MODIS sensor is on board the Terra and Aqua satellites of NASA launched in 1999 and 2002, respectively. It provides land surface and cloud data in 36 spectral bands within 0.4 to 14.4 mm of the electromagnetic spectrum. MODIS/Terra Data Outages. Last Update: April 15, 2021. The following table outlines major data outage periods since the start of the Terra mission. MODIS Payload Moderate Resolution Imaging Spectroradiometer (PFM on Terra, FM1 on Aqua) MODIS Bands: Spectrum, Wave length, Resolution, Swath width, Revisit time Back Satellite and Sensor database Search satellites All satellites Search sensors All sensors Launch schedule Glossary Important information The MODIS AOD used in this study is the MODIS/Terra C6 L3 merged DTDB AOD product for the period April 2000 to December 2015.

MODIS Terra Daily NDSI. The Normalized Difference Snow Index is used to identify snow, based on its characteristically higher reflectance in the visible portion of the spectrum compared to the mid-IR. NDSI is computed using the Green and Mid-IR bands, and has a range of -1.0 to 1.0.

Consequently, MODIS tracks a wider array of the earth’s vital signs than any other Terra sensor. For instance, the sensor measures the percent of the planet’s surface that is covered by clouds almost every day. Worldview Snapshots is a logical evolution of the Rapid Response system.

The Terra MODIS Vegetation Continuous Fields (VCF) product is a sub-pixel-level representation of surface vegetation cover estimates globally. Designed to continuously represent Earth's terrestrial surface as a proportion of basic vegetation traits, it provides a gradation of three surface cover components: percent tree cover, percent non-tree cover, and percent bare.

The MODIS instrument is operating on both the Terra and Aqua spacecraft. It has a viewing swath width of 2,330 km and views the entire surface of the Earth every one to two days. Its detectors measure 36 spectral bands between 0.405 and 14.385 µm, and it acquires data at three spatial resolutions — 250m, 500m, and 1,000m.

The NASA Worldview app provides a satellite's perspective of the planet as it looks today and as it has in the past through daily satellite images.

This resulted in a reduction in the overall Terra daytime coverage and many of the MODIS/Terra imagery layers have a slightly jagged appearance with less coverage over the northern high latitude regions. The Moderate Resolution Imaging Spectroradiometer (MODIS) is a payload imaging sensor built by Santa Barbara Remote Sensing that was launched into Earth orbit by NASA in 1999 on board the Terra (EOS AM) satellite, and in 2002 on board the Aqua (EOS PM) satellite. 2020-01-01 · Welcome to NASA Earth Observations, where you can browse and download imagery of satellite data from NASAs Earth Observing System. Over 50 different global datasets are represented with daily, weekly, and monthly snapshots, and images are available in a variety of formats.

This data set contains daily, gridded snow cover and albedo derived from radiance data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) on board the Terra satellite. Snow cover is identified using the Normalized Difference Snow Index (NDSI) and a series of screens designed to alleviate errors and flag uncertain snow cover detections.

MODIS/Terra Net Primary Production Yearly L4 Global 1km SIN Grid V055 The MOD17A3.055 dataset was decommissioned on April 6, 2020. Users are encouraged to use the new improved MOD17A3HGF.006 dataset. The MODIS/Terra Snow Cover Daily L3 Global 0.05Deg CMG (MOD10C1) data set contains snow cover and Quality Assessment (QA) data, latitudes and longitudes in compressed Hierarchical Data Format-Earth Observing System (HDF-EOS) format, and corresponding metadata.

Worldview is part of NASA’s Earth Observing System Data and Information System. EOSDIS makes the agency's large repository of data … With its sweeping 2,330-km-wide viewing swath, MODIS sees every point on our world every 1-2 days in 36 discrete spectral bands. Consequently, MODIS tracks a wider array of the earth’s vital signs than any other Terra sensor. For instance, the sensor measures the percent of the planet’s surface that is covered by clouds almost every day. Worldview Snapshots is a logical evolution of the Rapid Response system.
