Brief Description:

The International Comprehensive Ocean-Atmosphere Data Set (ICOADS) offers surface marine data spanning the past three centuries, and simple gridded monthly summary products for 2° latitude x 2° longitude boxes back to 1800 (and 1°x1° boxes since 1960)—these data and products are freely distributed worldwide. As it contains observations from many different observing systems encompassing the evolution of measurement technology over hundreds of years, ICOADS is probably the most complete and heterogeneous collection of surface marine data in existence.

 

Temporal Coverage:

·Monthly values for 1960/01 - 2011/11.
(IMPORTANT: The time period of these products is defined in two segments.)
·Following the Release 2.5 end date data are based exclusively on real-time GTS data with minimal quality control. These data should be considered preliminary and will be subject to change in new releases.

Spatial Coverage:

·1.0 degree latitude x 1.0 degree longitude global grid (180x360).
·89.5N - 89.5S, 0.5E - 359.5E.

*The netCDF files are subdivided into "standard" and "enhanced" products, which reflect the "trimming" (quality control) procedure used and the data mixture. In the standard products, the data have been edited using climatological 3.5 standard-deviation (sigma) limits, with the observations limited (as nearly as practical) to those from ships. In the "enhanced" products, in contrast, the data have been edited using broader 4.5 sigma limits to better represent extreme climate events, with observations from ships plus from other in situ marine platform types (e.g., drifting and moored buoys).
