International climate agreements will increasingly require their independent monitoring. A satellite-based, double-pulse, direct detection Integrated Path Differential Absorption (IPDA) Lidar with the capability to actively target point sources has the potential to usefully complement the current and future GHG observing system. This initial study uses simple approaches to determine the required Lidar characteristics and the expected skill of spaceborne Lidar plume detection and emission quantification. A Gaussian plume model simulates the CO2 or CH4 distribution downstream of the sources. A Lidar simulator provides the instrument characteristics and dimensions required to retrieve the emission rates, assuming an ideal detector configuration. The Lidar sampling frequency, the footprint distance to the emitting source and the error of an individual measurement are of great importance. If wind speed and direction are known and environmental conditions are ideal, an IPDA Lidar on a 500-km orbit with 2 W average power in the 1.6 \u00b5m CO2 absorption band, 500 Hz pulse repetition frequency, 50 m footprint at sea level and 0.7 m telescope diameter can be expected to measure CO2 emission rates of 20 Mt\/a with an average accuracy better than 3% up to a distance of 3 km away from the source. CH4 point source emission rates can be quantified with comparable skill if they are larger than 10 kt\/a, or if the Lidar pulse repetition frequency is augmented.<\/jats:p>","DOI":"10.3390\/rs9111137","type":"journal-article","created":{"date-parts":[[2017,11,8]],"date-time":"2017-11-08T12:38:48Z","timestamp":1510144728000},"page":"1137","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Potential of Spaceborne Lidar Measurements of Carbon Dioxide and Methane Emissions from Strong Point Sources"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1231-2813","authenticated-orcid":false,"given":"Christoph","family":"Kiemle","sequence":"first","affiliation":[{"name":"Deutsches Zentrum f\u00fcr Luft-und Raumfahrt (DLR), Institut f\u00fcr Physik der Atmosph\u00e4re, D-82234 Oberpfaffenhofen, Germany"}]},{"given":"Gerhard","family":"Ehret","sequence":"additional","affiliation":[{"name":"Deutsches Zentrum f\u00fcr Luft-und Raumfahrt (DLR), Institut f\u00fcr Physik der Atmosph\u00e4re, D-82234 Oberpfaffenhofen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5076-1559","authenticated-orcid":false,"given":"Axel","family":"Amediek","sequence":"additional","affiliation":[{"name":"Deutsches Zentrum f\u00fcr Luft-und Raumfahrt (DLR), Institut f\u00fcr Physik der Atmosph\u00e4re, D-82234 Oberpfaffenhofen, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2818-9290","authenticated-orcid":false,"given":"Andreas","family":"Fix","sequence":"additional","affiliation":[{"name":"Deutsches Zentrum f\u00fcr Luft-und Raumfahrt (DLR), Institut f\u00fcr Physik der Atmosph\u00e4re, D-82234 Oberpfaffenhofen, Germany"}]},{"given":"Mathieu","family":"Quatrevalet","sequence":"additional","affiliation":[{"name":"Deutsches Zentrum f\u00fcr Luft-und Raumfahrt (DLR), Institut f\u00fcr Physik der Atmosph\u00e4re, D-82234 Oberpfaffenhofen, Germany"}]},{"given":"Martin","family":"Wirth","sequence":"additional","affiliation":[{"name":"Deutsches Zentrum f\u00fcr Luft-und Raumfahrt (DLR), Institut f\u00fcr Physik der Atmosph\u00e4re, D-82234 Oberpfaffenhofen, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2017,11,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"43","DOI":"10.5194\/acp-11-543-2011","article-title":"A very high-resolution (1 km \u00d7 1 km) global fossil fuel CO2 emission inventory derived using a point source database and satellite observations of nighttime lights","volume":"11","author":"Oda","year":"2011","journal-title":"Atmos.
