Technological Cooperation with Cimel Electronique: A low-cost CO2 sunphotometer

A new low-cost sun photometer for total column CO2 measurements is being developed by Cimel Electronique in collaboration with the IARC and the Karlsruhe Institute of Technology.

Two new tilting filter photometer prototypes are tested and developed at Izaña Observatory. The IARC, together the IMK, performs the filter characterization, the development of new algorithms to derive CO2, and CO2 data validation against FTIR and in-situ measurements.
