DF 4901 – Diplomatarium Fennicum

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. MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (originally known as EOS AM-1) and Aqua (originally known as EOS PM-1) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Early in the mission, the MODIS Science Team decided to maintain a record of multiple data versions of Aqua- and Terra-derived MODIS products from a unique temporal bracket.

2020-09-11 The MODIS Surface Reflectance products (short names: MOD09A1, MOD09Q1, MOD09GA, MYD09A1, MYD09Q1, MYD09GA) provide an estimate of the surface spectral reflectance of Terra and Aqua MODIS Bands 1 through 7 corrected for atmospheric conditions such as gasses, aerosols, and Rayleigh scattering (Vermote, 2015).

C6 biases and trends easily exceed 1 K in bands 27 and 30 over the eight year period in Figure 2, indicating that the MODIS C6 L1B radiances of these bands are not useful for climate science.

It has a viewing swath width of 2,330 km and views the entire surface of the Earth every one to two days. Collection-5 MODIS/Terra Vegetation Indices products are Validated at Stage 2, meaning that accuracy has been assessed over a widely distributed set of locations and time periods via several ground-truth and validation efforts.
