TABLE 4.
Measured irradiance in mol PAR photons m−2 d−1 on a horizontal surface, the north reactor panel, and the south reactor panel (top) during the batch dilution experiments. Measured peak light intensities in μmol PAR photons m−2 s−1 during the day. Measured ambient temperature in °C, and measured temperatures in the north and south reactor panels (bottom). Irradiance and/or temperature data was incomplete on days 9, 12, 14, and 22 of run 1, days 5 and 9–13 of run 3, and days 9 and 14 of run 4. Data on these days were not incorporated in the results shown below.
