The Science of PSMI

Current PSMI Activities

PSMI GOALS

  1. Reduce major systematic errors and biases in GCMs used for climate variability prediction and climate change projection
    • Climate variability prediction includes subseasonal-to-decadal timescale prediction and simulations. Beyond decadal timescales, simulations must use uncertain forcings (e.g. for anthropogenic CO2) and are described as projections. Systematic errors and biases of concern are those that exist in multiple climate models. Major errors are those which have a large impact on climate simulations. Established examples include: representation of stratocumulus, eastern ocean boundary SST, excessive cold tongue, double ITCZ, weak tropical variability, storm track placement and variations, and mid-latitude air-sea interaction.
  2. Use process studies to quantify climatically important processes and to provide guidance for extending long-term in situ and satellite observations
    • In addition to their primary function of improving understanding of key processes, process studies should be designed to leave a continuing legacy for the overall climate observational record. This legacy can include: (a) guidance for placement of long-term sparse observing platforms; (b) calibration of satellite products, enabling extension of the climate record into the past through existing satellite data.
  3. Ensure that process studies lead to climate model improvement
    • Many field programs explore climatically important processes, combining in situ and remote observations on a variety of scales. Combined with process models, these can develop understanding of the process. Our goal is to ensure that this understanding translates into improved climate GCMs. That may involve: consultation on process study design, recommendation for supplemental modeling and/or field activities, and guidance for climate process teams.
  4. Facilitate collaborations with other national and international partners such as international CLIVAR, GEWEX, OCCC.
    • We welcome and value the opportunity to collaborate with other programs on modeling and observational activities of mutual interest and recognize that these opportunities can result in leveraged resources and added scientific benefits.
