Obs4MIPs About Us

Long Name Obs4MIPs
Description OVERVIEW

A wide variety of observationally-based datasets are used for climate model evaluation. Obs4MIPs refers to a limited collection of well-established and documented datasets that have been organized according to the CMIP5 model output requirements and made available to the research community in the same way CMIP5 is accessed. Each Obs4MIPs dataset corresponds to a field that is output in one or more of the CMIP5 experiments. This technical alignment of observational products with climate model output greatly facilitates model data comparisons. Guidelines have also been developed for Obs4MIPs product documentation that is of particular relevance for model evaluation. More recently, the World Climate Research Program (WCRP)'s Data Advisory Council (WDAC) has initiated a Task Team to provide governance and guidance to obs4MIPs (see Governance tab).


To summarize, products available via Obs4MIPs are:
1. Directly comparable to a model output field defined as part of CMIP5
2. Open to contributions from all data producers that meet the Obs4MIPs requirements (see below)
3. Well documented, with traceability to track product version changes
4. Served through ESGF

When the CMIP6 experiments are finalized, obs4MIPs will update its protocols to include CMIP6 variables.

HISTORY

NASA/JPL and DOE/PCMDI initiated this activity with a focus on monthly mean near global satellite products and a limited selection of higher frequency data. To date, a variety of satellite products have been contributed to obs4MIPs from NASA. Cloud related datasets have been contributed by the CFMIP-OBS activity (http://climserv.ipsl.polytechnique.fr/cfmip-obs/), and some data from ESA (http://www.esa.int/ESA) is now available.

The CMIP5 simulation protocol (Taylor et al., 2011) is utilized as the guideline for identifying which products to make available via the ESGF, in particular: which variables, and for what periods, temporal frequencies, and spatial resolutions. A planning workshop sponsored by NASA and the DOE brought together experts in satellite observations and climate model diagnosis (held at PCMDI in October 2010, Gleckler et al., 2011). These initial efforts along with a summary of the activity were also highlighted in a BAMS In-Box article (Teixeira et al., 2014).


SPONSORSHIP

This effort has been initiated with support from the United States' National Aeronautical and Space Administration (NASA) and Department of Energy (DOE) with the intent of enabling additional data providers to contribute products. In addition, the World Climate Research Program (WCRP)'s Data Advisory Council (WDAC) has initiated a Task Team to provide governance and guidance to obs4MIPs (see Governance tab).
