This file contains the monthly mean baseline (background) methane (CH4) concentration measured at the Kennaook / Cape Grim Baseline Air Pollution Station (KCGBAPS), located near the north-west tip of Tasmania, Australia. KCGBAPS is funded and managed by the Australian Bureau of Meteorology, and the scientific program is jointly supervised with CSIRO Oceans & Atmosphere. Please acknowledge these two institutions if these data are used in publications or presentations. For more information on Kennaook / Cape Grim please see: http://www.csiro.au/greenhouse-gases/ https://www.csiro.au/en/Research/OandA/Areas/Assessing-our-climate/Greenhouse-gas-data http://www.bom.gov.au/inside/cgbaps/ The CH4 units are parts per billion in dry air (ppb). The most recent year of data is provided in this file on a provisional basis only. These data may be subject to further revision. CSIRO & the Bureau make every effort to produce the most accurate and precise measurements possible. However, they reserve the right to make corrections to the data based on recalibration of standard gases or for other reasons deemed scientifically justified.
