Calculating atmospheric partial pressure of oxygen

[QUOTE="GhostLineage, post: 6863661, member: 734198"] Thanks for your reply. I should have been more specific that I'm looking to calculate an estimate of partial pressure of oxygen for points across a landscape without already knowing the atmospheric pressure. I have lat/long, altitude, and other variables accessible from WorldClim. I see papers like this: [URL='https://bmcgenomics.biomedcentral.com/articles/10.1186/1471-2164-14-631']https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3852963/[/URL] where partial pressure of oxygen is inferred using altitude, but no other environmental variables (see figure 1). But then I see sources describing how temperature and latitude affect barometric pressure, and can increase hypoxia (on the first page): [URL]https://eu-ireland-custom-media-prod.s3-eu-west-1.amazonaws.com/UKMEAEU/eSample/9780323359429-sample-chapter.pdf[/URL] They talk about how if the summit of Mt. Everest were at the same latitude as Denali, Everest would be impossible to climb without supplemental oxygen. I'm hoping to find a nice equation out there like the one that Zhao et al. 2013 (posted above) used, but includes temperature, and maybe other factors like latitude and humidity. [/QUOTE]
