Extended Data Fig. 2: Comparison of observed and model low cloud fraction and the normalized modeled temperature response from two marine cloud brightening schemes.
From: Diminished efficacy of regional marine cloud brightening in a warmer world
a, Mean 1984–2009 observed low cloud fraction from March to November from the International Satellite Cloud Climatology Project (ISCCP) (see ‘International Satellite Cloud Climatology Project (ISCCP) dataset’ in Methods). The magenta (mid-latitude) and green (subtropical) contours show the average cloud brightening regions from March to November (includes grid cells brightened in at least half of the seeding months). The black contour shows the Western U.S. target region. b, 1984–2009 ensemble mean low cloud fraction from March to November from the CESM2 Large Ensemble (LENS2) ensemble mean. c, d, Reference height temperature response normalized by the absolute global mean forcing due to (c) 2010 mid-latitude and (d) subtropical MCB. Top-right values show the area-weighted global mean.
