Primary Production, an Index of Climate Change in the Ocean: Satellite-Based Estimates over Two Decades. Although this is a substantial increase in the estimate of primary production, the results of the sensitivity analysis in which the photosynthesis versus irradiance parameters were varied by ±1 standard deviation and, importantly, the observed trends in regional and global annual primary production are largely unchanged. The main corrections increased our estimate of global annual primary production on average by +23.9% between 1998 and 2018, while the correction of the rounding error in the PAR products increased global annual primary production between 2003 and 2018 by +0.9%. Global annual primary production remained close to the range of earlier observations (32.0-70.7 Gt C y SP -1 sp ) [2,4,5,22] when both P-I parameters were adjusted by +1 standard deviation (+1 SD) (70.8-76.2 Gt C y SP -1 sp ), but adjustments by -1 standard deviation (-1 SD) resulted in considerably lower global annual primary production rates (25.7-27.8 Gt C y SP -1 sp ).
