Observation trend files

These files contain daytime and nighttime observation trends (K/decade) in the unadjusted data and the adjusted data from 100 experiments (see Titchner et al., 2009 for more information). Global (70S-70N), Tropical (20S-20N), Northern Hemisphere (NH) extra tropical (20N-70N) and Southern Hemisphere(SH) extra tropical (70S-20S) trends for the pre-satellite period (1958-1977), satellite period (1978-2003) and the full period (1958-2003) are given. They have been calculated for the standard pressure levels as well as the lower tropospheric (T2LT), mid tropospheric (T2) and lower stratospheric (T4) Microwave Sounding Unit (MSU) equivalent layers.
