Purpose

 

This tool allows importing Generic Atmospheric Correction Online Service for InSAR (GACOS).

 

Technical Note

 

This tool allows importing Generic Atmospheric Correction Online Service for InSAR (GACOS) data. GACOS utilises the Iterative Tropospheric Decomposition (ITD) model (Yu et al., 2017) to separate stratified and turbulent signals from tropospheric total delays, and generate high spatial resolution zenith total delay maps to be used for correcting InSAR measurements and other applications. For more details visit http://www.gacos.net/

 

Before importing the GACOS data make sure you requested and downloaded them from the online interface respecting the provider's policy.
