P0032.2

Diurnal cycle, hour/day matrix view

P0032.2 product shows the evolution of the molar fraction hour-by-hour, for each day of the year, for the given site/species. Each small colored vertical tick represents the hourly mean of the molar fraction of the site/species names in plot's title, at the local hour given in the Y-axis legend, for the day of year given in the X-axis legend. 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.
• X-axis: local day of year 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.
