P0004.5

NRT - Air - Whole network view - Last rolling year

P0004.5 product shows the last year concentration evolution. For a given network, a species and a selection of daily hours, the plot shows the evolution over time of the molar fraction measured at each highest sampling height of each of the network's sites.

Details:

• Data used: hourly means of highest sampling height (continuous timeseries), filtered by hour local time (day: 12:00 to 16:00 ; night: 00:00 to 04:00 ; full day: no filter), then averaged by day.
• Y-axis: Sites sorted by descending latitude, and their highest sampling height.
• Colored bars: One vertical line per day per site. The color refers to the colored scale on the right. Molar fraction above λ+2σ are dark red, molar fraction below λ-2σ are dark blue.
• Timeframe: the last 12 full months
