The Ocean Biology DAAC produces near real-time (NRT) products using the best-available combination of ancillary data from meteorological and ozone data. As such, the inputs and the calibration used are less than optimal. Near real-time products provide a snapshot of the data during a short time period within a single orbit.

The RemoTAP Level-3 Chlorophyll-a (Chla) product provides estimates of surface chlorophyll-a concentration, a commonly used proxy for phytoplankton biomass. Values are derived using the RemoTAP algorithm.

In the current version, the variable is named chlor_a, with the long name “Chlorophyll-a concentration, OCI algorithm.” The variable and its long name will be updated in a future release to correctly reference the RemoTAP algorithm.

Geophysical variable included:
• chlor_a – Chlorophyll concentration (mg m⁻³)
