Short summary
We present the results of tests of CRDS instruments in the laboratory (47 instruments) and in the field (15 instruments). We demonstrate that, thanks to rigorous testing, newer models generally perform better than older models, especially in terms of reproducibility between instruments. In the field, we see the importance of individual diagnostics during the installation phase, and we show the value of calibration and target gases that assess the quality of the data.
