This page provides access to a climatological dataset prepared from the ACE-FTS satellite measurements. It provides useful information and links relevant to this dataset and the SCISAT/ACE mission.
Presently, a quality controlled climatology has been created for each of the 14 baseline species for ACE-FTS (O3, H2O, CH4, N2O, CO, NO, NO2, N2O5, HNO3, HCl, ClONO2, CCl3F, CCl2F2, and HF). Also, a combined NOy climatology has been prepared from the NO, NO2, N2O5, ClONO2, HNO3, and HNO4 (research product) results from ACE-FTS.
The retrieval version used is the ACE-FTS version 2.2 (including updates for O3 and N2O5). The baseline species were validated and these results are available from the ACE Validation Special Issue of ACP
The climatological fields are provided on a monthly and three-monthly basis (DJF, MAM, JJA, SON) at 5 degree latitude and equivalent latitude spacing and on 28 pressure surfaces. Please consult the references below for further information.

How to Cite
In any publications using ACE data, such as this climatology, it is important to acknowledge the Canadian Space Agency for the funding of the SCISAT satellite. Any text that recognizes the Canadian Space Agency as funding the ACE Mission is permitted, but we have provided a sample to use that meets this requirement. This simple statement has been used in many publications with ACE data.
