Northwest Atlantic per-pixel spring bloom metrics derived from OC-CCI POLY4 satellite Chlorophyll-a, 1998-present

NWA OCCCI spring bloom metrics 2024

cdm_data_type = Grid
VARIABLES (all of which use the dimensions [time][latitude][longitude]):
t_start (Day of year of the start of the spring phytoplankton bloom)
t_duration (Duration of the spring phytoplankton bloom, days)
amplitude_real (Maximum concentration during the spring phytoplankton bloom period, mg/m3)
magnitude_real (Total chlorophyll-a produced during the spring phytoplankton bloom period, days*mg/m3)
annual_mean (Average chlorophyll-a over the year, mg/m3)
NRMSE_bloom (Root mean square error between the fitted Gaussian and real chl-a values during the bloom period, normalized to amplitude_real, mg/m3)
percent_dineof (Percentage of days with pixel values estimated using DINEOF)
