NCEP/NCAR Reanalysis Data, Sea-Level Pressure

  • The dataset provides sea level pressure data from 1948 to near present with 6-hour temporal and 2.5-degree spatial resolution.

  • This dataset is part of the NCEP/NCAR Reanalysis Project, which aims to produce atmospheric analyses using historical and current data.

  • The data includes a band named 'slp' representing sea level pressure in millibars with estimated min and max values.

  • There are no restrictions on the use of these datasets.

  • This dataset can be explored and analyzed using the Google Earth Engine platform.

Description

The NCEP/NCAR Reanalysis Project is a joint project between the National Centers for Environmental Prediction (NCEP, formerly "NMC") and the National Center for Atmospheric Research (NCAR). The goal of this joint effort is to produce new atmospheric analyses using historical data as well as to produce analyses of the current atmospheric state (Climate Data Assimilation System, CDAS). The NCEP/NCAR Reanalysis 1 project is using a state-of-the-art analysis/forecast system to perform data assimilation using past data from 1948 to the present. The data have 6-hour temporal resolution (0000, 0600, 1200, and 1800 UTC) and 2.5 degree spatial resolution.
