P0034.3

Vertical Gradient (Diff-to-max), hour/day matrix view

P0034.3 product shows the evolution of the molar fraction difference to highest level hour-by-hour, for each day of the year, for the given site/species. Each box plot displays the difference between the molar fraction of the air measured at the sampling height named in Y-axis title, and the molar fraction of the air measured at the site's maximum sampling height. The black (dotted) lines represents the time of the sunrise and sunset for each day.

Details:

• Data used: hourly mean of GHG air data's molar fraction, continuous time series. Each tick represents: [hourly mean of current sampling height] - [hourly mean of highest sampling height]
• Box plot: one box plot per sampling height below the highest site's sampling height.
• X-axis: local day of year at the site.
• Y-axis: local hour of day at the site.
• Vertical colored tick: the two extremes of the color scale (dark blue and dark red) are the mean ±2σ.
• Black lines: the black line links each sunrise times, the black dotted line links each sunset times.
• Timeframe: one rolling year, as defined in plot's subtitle
• Species: as given in plot's title. There is one separate plot file per species measured in the site.
