MODIS

Currently available in AirLogic: The Aerosol Optical Depth Measurement

The MODerate resolution Imaging Spectroradiometer (MODIS) is a key instrument aboard the Terra (originally known as EOS AM-1) and Aqua (originally known as EOS PM-1) satellites, launched in 1999 and 2002 respectively. Currently available in AirLogic is the Aerosol Optical Depth measurement, with daily global coverage and resolution 1km/pixel. Aerosol optical depth is a measure of the extinction of the solar beam by particles in the atmosphere (dust, smoke, pollution). It is a dimensionless number that is related to the amount of aerosol in the vertical column of atmosphere over the observation location. MODIS data is available from 01/01/2018 and is updated every other day.

Type:
Satellite (NASA Terra and Aqua)

Time Range Available:
April 2020 – Present

Resolution:
1 km x 1 km

Update Frequency:
Every Day

In AirLogic, the default time period display is daily. In the case of TROPOMI and MODIS, the value displayed in the chart for a selected date corresponds to the satellite measurement at the local overpass time for that date. Setting the time period to monthly/quarterly you can obtain a monthly/quarterly rolling average for the selected metric.
