Graph showing the long term average daily NEP (Net Ecosystem Productivity) and the average accumulated CO2 removal from the atmosphere at the Alice Holt flux site. Columns below the zero line (day 0 to 140 & 280 to 365) indicate that the forest is acting as a net source for CO2. For the summer period (day 141 to 279) columns are above the zero line indicating that forest is acting as a net sink. The solid line indicates the average accumulated carbon balance for the site.
