A few falling low pressure events, similar to the Loscoe event, have occurred over the recent festive period. GGS’ continuous monitoring have captured the extent in which ground-gases have responded to such falling pressure at several locations spread across the UK. The correlation between methane and atmospheric pressure is clear in the graph below.
The continuous monitoring data collected from one of our GasClam devices on a site in Scotland, recorded a pressure fall of 23 millibars over six hours. During this period the GasClam recorded a pressure fall of 6 millibars in just one hour! And to a low of 938 millibars!! The meteorological office recorded the maximum pressure fall during the Loscoe event to be 4.8 millbar fall in one hour. These falling low pressure events, similar to the above, seem to be a more frequent occurrence due to climate change.
Over the next few weeks GGS will be collating the continuous monitoring data from several other sites located elsewhere in the UK. Watch this space!
