ACE-FTS NOy Climatology - Version 2.2


A combined NOy climatology was prepared using the version 2.2 NO, NO2, N2O5, ClONO2, HNO3, and HNO4 (research product) results.

The climatological fields are provided on a one- and three-month basis (DJF, MAM, JJA, SON), at 5 degree latitude spacing, and on 33 pressure surfaces. Please consult the associated reference and the data set 'ReadMe' files 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 recorecognizes 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.

Sample ACE Acknowledgement:

The Atmospheric Chemistry Experiment (ACE), also known as SCISAT, is a Canadian-led mission mainly supported by the Canadian Space Agency (CSA).
