Trends in radiosonde-based temperatures and lower-tropospheric lapse rates are presented for the time periods 1959-97 and 1979-97, including their vertical, horizontal, and seasonal variations. A novel aspect is that estimates are made globally of the effects of artificial (instrumental or procedural) changes on the derived trends using data homogenization procedures introduced in a companion paper (Part I). Credibility of the data homogenization scheme is established by comparison with independent satellite temperature measurements derived from the microwave sounding unit (MSU) instruments for 1979-97. The various analyses are performed using monthly mean temperatures from a near-globally distributed network of 87 radiosonde stations.
