The following list shows the investigators & institutions that have data on tropospheric concentrations of trace concentrations derived from satellite data.

It should be realised that, at the present time, most tropospheric data is obtained with experimental algorithms on a single-data-set basis, and that the data is upgraded as improvements are made to the methods of treatment. Thus each set of data often represents a considerable effort on the part of the principal investigator and his/her research group. It is essential therefore that the PI and his/her group have a chance themselves to evaluate the data themselves and that, if data is released to others, the PI and his/her group receive a proper acknowledgement, probably in the form of co-authorship of any resulting publications.

To obtain the data listed here, it is necessary to contact and to come to an agreement about the use to which the data will be put with the principal investigator shown.
