The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Precipitation and sea level pressure model output under varying atmospheric scenarios centered over South Africa from 1921-01-01 to 2100-12-31 (NCEI Accession 0220095) |
| Abstract: | This archival information package contains NetCDF files of monthly mean precipitation and sea level pressure model output. The precipitation grid is centered over South Africa and the more densely packed sea level pressure grid is for the entire southern hemisphere. More precisely, this dataset contains a subset of the SPEAR_MED, SPEAR_LO, FLOR and FLOR_FA large ensembles (30 members) used for the results published in the study "Increasing risk of another Cape Town Day Zero drought in the twenty-first century". Specifically, we provide the precipitation field (unites: kg/m2/s) over a domain centered over South Africa and Sea Level pressure over a Southern Hemisphere domain. All the data is at monthly resolution (monthly means). For SPEAR_MED, we provide data from four different numerical experiments: (1) a long-term 3,000-yr control simulation (CTRL) to evaluate unforced natural variability; (2) an ensemble driven by natural forcing only (NATURAL, 1921-2100) to provide a baseline with only natural forcing (i.e., volcanic eruptions and solar cycles); (3) two ensembles driven by natural and anthropogenic (greenhouse gases, anthropogenic aerosols, ozone) forcing according to the intermediate Shared Socioeconomic Pathway SSP2-4.5 and SSP5-8.5 (1921-2100) developed for the Coupled Model Intercomparison Project Phase 6 (CMIP6). For SPEAR_LO, we provide data from three different numerical experiments: (1) a long-term 5,000-yr control simulation (CTRL); (2) an ensemble driven by natural forcing only (NATURAL, 1921-2100); (3) one ensembles driven by natural and anthropogenic (greenhouse gases, anthropogenic aerosols, ozone) forcing according to the intermediate Shared Socioeconomic Pathway SSP5-8.5 (1921-2100). For FLOR provide data from three different numerical experiments: (1) a long-term 2,200-yr control simulation (CTRL); (2) an ensemble driven by natural forcing only (NATURAL, 1921-2100); (3) one ensembles driven by natural and anthropogenic (greenhouse gases, anthropogenic aerosols, ozone) forcing according to the intermediate Radiative Concentration Pathway RCP8.5 (1921-2100). For FLOR_FA provide data from three different numerical experiments: (1) a long-term 3,500-yr control simulation (CTRL); (2) an ensemble driven by natural forcing only (NATURAL, 1921-2100); (3) one ensembles driven by natural and anthropogenic (greenhouse gases, anthropogenic aerosols, ozone) forcing according to the intermediate Radiative Concentration Pathway RCP4.5 (1941-2050). |
