Abstract
The International Surface Pressure Databank (ISPD) is the world's largest collection of global surface and sea‐level pressure observations. It was developed by extracting observations from established international archives, through international cooperation with data recovery facilitated by the Atmospheric Circulation Reconstructions over the Earth (ACRE) initiative, and directly by contributing universities, organizations, and countries. The dataset period is currently 1768–2012 and consists of three data components: observations from land stations, marine observing systems, and tropical cyclone best track pressure reports. Version 2 of the ISPD (ISPDv2) was created to be observational input for the Twentieth Century Reanalysis Project (20CR) and contains the quality control and assimilation feedback metadata from the 20CR. Since then, it has been used for various general climate and weather studies, and an updated version 3 (ISPDv3) has been used in the ERA‐20C reanalysis in connection with the European Reanalysis of Global Climate Observations project (ERA‐CLIM). The focus of this paper is on the ISPDv2 and the inclusion of the 20CR feedback metadata. The Research Data Archive at the National Center for Atmospheric Research provides data collection and access for the ISPDv2, and will provide access to future versions.
Highlights
The International Surface Pressure Databank (ISPD) is the world’s largest collection of global surface and sea-level pressure observations
Since its inception in 2002, its development has been facilitated by cooperative efforts between the Global Climate Observing System (GCOS)/World Climate Research Program (WCRP) Working Group on Observational Data Sets for Reanalysis [2007 to 2011], and the ongoing efforts of the GCOS Working Group on Surface Pressure and the international Atmospheric Circulation Reconstructions over the Earth initiative (ACRE, Allan et al, 2011)
The inclusion of various versions of both International Comprehensive Ocean–Atmosphere Data Set (ICOADS) and International Best Track Archive for Climate Stewardship (IBTrACS) in ISPD version 2 (ISPDv2) was the result of using the most up-to-date data that were available during the assimilation into the Twentieth Century Reanalysis (20CR; Compo et al, 2011)
Summary
The International Surface Pressure Databank (ISPD) is the world’s largest collection of global surface and sea-level pressure observations. The ISPD version 2 (ISPDv2) covers the period 1768–2012 It merges data from three input components: observations from land stations, marine observing systems, and tropical cyclone best track pressure reports. The marine component consists of sea-level pressure observations extracted from the International Comprehensive Ocean–Atmosphere Data Set (ICOADS, Woodruff et al, 1998; Parker et al, 2004; Woodruff et al, 2005; Worley et al, 2005; Woodruff et al, 2011), a global ocean marine meteorological and surface ocean dataset that is considered the most complete of its kind.
