This interactive report is run on a weekly basis and provided to London Borough of Camden on 18 February 2024 morning. It shows a weekly summary for the period Monday February 12 2024 to Sunday February 18 of up to date provisional monitoring data for the site and presents a simple summary of the current concentrations in the context of recent weather patterns and anticipated short term weather. It can be used by the Local Authority to monitor current levels, understand and explain any recent episodes and to subjectively forecast and act on the potential for evolving episodes. The reports provides:
Concentrations are provisional, pending ratification. All gaseous pollutant mass units are at 20 degrees Celcius and 1013 mb. NOX mass units are NOX as NO2 μgm-3.
Many elements of the report are interactive and can be intuitively manipulated by the reader to provide a more useful and engaging information resource. For example, the floating table of contents to the left, follows the user throughout the report and is a simple, convenient, expanding/collapsing navigation tool. The tables display the first 10 rows initially but the user can expand this to their own preference to see the complete table in a single view using the dropdown option. The user can also search the table using the box to filter the appropriate entries, for example by a specific start or end date, by site, by metric or by site type etc. Other interactive components of the report are briefly summarised in each relevant section.
The data provided in the time series shows the year to date concentrations, appended to include the most recent week (week beginning 12/02/2024). A closer inspection of concentrations (e.g. for the last week) can be obtained by clicking and dragging a box over the portion of the plot of interest to zoom in. Reverting back to the whole plot can be done by double clicking anywhere on the plot. Hovering the mouse cursor over the plot area will display the exact time and date stamp for that position on the plot and the exact value associated with it in the top right of the plot area.

Tables below show the tabulated hourly measurement data for the reported week. The table can be searched or filtered and the number of records displayed can be altered. Please note, these data are provisional and subject to change.
The table presented below shows summary statistics for the week. Please note, these data are provisional and subject to change.
The back trajectory plot shows data from the HYSPLIT forecast model (NOAA HYSPLIT). This shows the air mass back trajectories for the previous day (2024-02-17), the trajectory for the current day (2024-02-18) and the forecast for the coming days.
Figure 6: Air mass back trajectories for 2024-02-17 and 2024-02-18, as well as forecasts for the coming 3 days.
Some examples of air mass origins and their impact on measured concentrations are described below:
Wind speeds and directions can be seen in even more detail in the dynamic map in the section below which shows strong winds as larger arrows and light winds as smaller arrows.
The animation and daily forecast bar below show the weather forecast in London for coming days. The animation is interactive: press the play button at the bottom of the animation to view the animated forecast. Hover the cursor over the animation and a bar to the right hand side will appear. From this bar the user can select to view the forecast wind speed and direction, cloud cover, temperature, rain, waves or pressure. This weather forecast is sourced from Windytv and is the current forecast for the day at which this document is viewed (and therefore is directly relevant at the time the report is provided but which will not refer to the period that monitoring data covers if viewed at a later time).
