| CIRE Algorithm Specification | |
The CIRE operator algorithm computes the
Chlorophyll Index Red
Edge from a given product.
The CIRE results from the following equation:
CIRE = (N / RE1) - 1
, where:
The bands are:
- RE1 is the Red Edge 1 band
- R is the Red band
- N is the NIR band
Also the processor computes an additional flags band called 'cire_flags' with the following bit coding:
| Bit Position | Description |
|---|---|
| Bit 0 | The computed value for CIRE is NAN or is Infinite |
| Bit 1 | The computed value for CIRE is less than -1 (minus one) |
| Bit 2 | The computed value for CIRE is greater than 1 (one) |
