Data are in self-describing HDF 4.2 format. Refer to global and data layers attributes for more information.
Suggested usage of the 16-bit quality flags (QF) are:
- for general applications, use data with the lowest bit cleared (QF AND 0x0001 == 0);
- for high-accuracy applications, use only data with the lowest two bits cleared (QF AND 0x0003 == 0);
- for advanced usage of individual QC checks, refer to the definition of individual QFs.
Note that all statistics presented in this website are based on the (QF AND 0x0001 == 0) condition.
Please be advised that the quality flags are only intended for sea surface temperatures. Other measurements have not been quality controlled.
