Sentences with phrase «include polar orbiting»

The UKMO series (as in Figure 2.5 a) does not include polar orbiting satellite data because of possible time - varying biases in them that remain difficult to correct fully (Reynolds, 1993) though the NCEP (National Centers for Environmental Prediction) data (adapted from Smith et al., 1996 and Reynolds and Smith, 1994), starting in 1950, do include satellite data after 1981.
