The NIST Greenhouse Gas and Climate Science Program supports several projects conducted by the Physical Measurement Laboratory's (PML), Time and Frequency Division.
| Mid-Infrared Sources and Techniques for Greenhouse Gas Detection – (S. Diddams and N. Newbury, PML) Goal: to develop broadband mid infrared frequency comb sources and spectroscopic sensing techniques for quantitative greenhouse gas detection in support of climate science. |
| Greenhouse Gas Monitoring using Fiber Frequency Combs – (N. Newbury and S. Diddams, PML) Goal: to develop a novel frequency comb-based sensor for the accurate and precise measurement of greenhouse gases over kilometer-scale open air paths. This system can support future regional studies as well as provide truth data for the validation of satellite-based systems. |
