The only climate data that goes into the models is grid data — the albedo, elevation, terrain type and average cloud cover of each grid point. (opinion-nation.blogspot.ru)
These changes can be found in both global average cloud cover and in each of the six 30 °C - latitude bands. (c3headlines.com)
«we estimate that less than 23 %, at the 95 % confidence level, of the 11 - year cycle changes in the globally averaged cloud cover observed in solar cycle 22 is due to the change in the rate of ionization from the solar modulation of cosmic rays.» (skepticalscience.com)
