5.2 Glossary

The Instantaneous Field of View (IFOV) is defined as the solid angle over which an optical system is sensitive to incoming radiation at an instant in time. The IFOV, in the AATSR Instrument Performance Requirements, is taken to be defined by an optical field stop. Optical effects such as diffraction and defocusing are excluded from this definition of the IFOV.

Note: Certain specific terms relating to the AATSR data processing algorithms are also defined in Section 2.3. Definitions and Conventions
