Estimates of ocean ${\rm CO}_2$ uptake from global ocean biogeochemistry models and ${\rm p{CO}}_2$-based data-products differ substantially, especially in high latitudes and in the trend of the ${\rm CO}_2$ uptake since 2000. Here, we assess the effect of data sparsity on two ${\rm p{CO}}_2$-based...
