  • During studies of oxygen isotope : temperature relationships for tree rings in the Canadian Rockies, the AA. noted differences in oxygen isotope ratios between samples from compression wood and normal radii in the same stem. This paper briefly
  • 1990
  • The A. presents data concerning radiative fluxes measured directly on a meadow and on a crop field during 1982-1984. Indirect methods of estimating radiation balance components were also discussed. The results of the field measurements were compared
  • 1990
  • This review traces the theory as far back as 1827, highlighting new directions and significant advances over that time. Four main themes can be discerned : 1) certain radiatively active gases are responsible for warming the planet| 2) that humans
