1HIRDLS Relative Accuracy - based on a single scan; improved relative accuracy is possible by averaging scans.
2 Two global maps/day means day and night, respectively;
3 G represents Global Coverage,
4 Special mode gives 250 x 250 km spacing, for 7 channels (T, O3, H2O, HNO3, aero)
5 Indicated resolution is FOV size of temperature channels, since temperature information goes into retrieval of all other products. Product resolution depends on over-sampling, noise, and data processing, and is expected to be better.
6 Profiles will extend beyond indicated limits, with reduced relative accuracy.
7 Altitude range strongly dependent on aerosol loading
8 Can be extended hydrostatically from 7-80 km
