MODIS

MODIS Collection 6.1 public release has begun

19 October 2017

The Collection 6.1 (C6.1) reprocessing of MODIS Atmospheres data products, including Deep Blue, has begun! At the time of writing, MODIS Terra data from 2000 to mid-2008 are available; additional data are added to the archive as they are processed.

Time series of VIIRS gain correction factors

New paper published about MODIS/VIIRS cross-calibration and improvement of aerosol retrieval

Time series of spectral gain corrections developed in the study, to bring MODIS and VIIRS into radiometric consistency. Red lines indicate the correction and shaded grey the one standard deviation of correction estimates within each month.

 

Validation of the ASHE algorithm, from Lee et al (2016)

New papers in Aerosol and Air Quality Research special issue

This figure from Lee et al. (2016) shows (top) time series of ASHE and MPLNET aerosol top height (ATH), (middle) VIIRS and AERONET AOD, and (bottom) ASHE and AERONET SSA from the complete algorithm (left) and simplified algorithm (right). Only best QA data are shown. The MPLNET and AERONET data are presented only if there are ASHE retrieved ATH data, while the gray dots represent the full MPLNET/AERONET data records. The black vertical line separates 2013 and 2014.

We are pleased to announce that select MODIS Collection 6 Atmospheres data products, including Deep Blue aerosol data, are now available on the NASA Worldview satellite imagery browsing tool. At present, data from 2007-2015 are currently available. Earlier years, as well as 2016 data (and near-real-time availability), are being added.

Key features of Worldview include:

Aerosols - above - clouds article featured as an EOS research spotlight

The American Geophysical Union (AGU) have selected our recent article about monitoring aerosols above clouds for a Research Spotlight. The Spotlight has been published in EOS and you can read it here.
