<span style="font-family: courier new,monospace;"> NC_GLOBAL#comment=GFDL experiment name = CM2.1U-H2_SresA2_W1. PCMDI experiment name = SRESA2 (run1). Initial conditions for this experiment were taken from 1 January 2001 of the climate of the 20th century experiment named CM2.1U-D4_1860-2000-AllForc_H2. Several time varying forcing agents used during the first 100 years of this CM2.1U-H2_SresA2_W1 experiment were based on output of the MOZART global atmospheric chemistry climate model when driven with the SRES A2 emission scenarios. For the CM2.1U-H2_SresA2_W1 experiment volcanic aerosols were zero, land surface cover types were time invariant, and solar irradiance varied seasonally based upon late 20th century averages but with no interannual variation.</span><br style="font-family: courier new,monospace;">
