SO&P: ECHO-G Sea level pressure

erik : "Erik-the-red" 1000-1990 all forcings

Important notes regarding the ECHO-G data:

Do not redistribute data to others outside the SO&P project.

GKSS or FUB may require co-authorship (depending on the level of their involvement), but they certainly want to be informed about what analyses you are using the ECHO-G data for. Please contact Julie Jones for the erik data or Irina Fast for the enat data (see SO&P participants table) and keep them informed.

To ensure collaboration between SO&P partners, please refer to the list of ongoing/planned model-data comparisons. Please contact others who have listed an interest in the same area, to initiate collaboration. To add your planned areas of model-data work to the list, email Tim Osborn.

Climate drift, unrelated to the external forcings, may be present in the ECHO-G simulations. An appropriate ECHO-G control simulation for assessing and removing any drift has not yet been performed. Data users should take this into account when using this data.

Please inform Tim Osborn of any errors that you find in the data.

Obtaining fields of model data

Fields of model data, covering the entire globe, are available in netCDF format only (please email Tim Osborn if you cannot use netCDF files). For monthly and seasonal-mean data, there is usually one file for each decade (though not always and the filenames or headers will make it clear when this is not the case). For annual data there are usually separate files for each year.

The netCDF header contains all the information about coordinates and units that you need.

You have two options for downloading the files:

Use wget with the command listed below (click here to obtain the wget software, to understand its options and for an explanation of its advantages):

wget --mirror --no-parent --no-directories --accept=nc --http-user=soapech --http-passwd=od2004 http://www.cru.uea.ac.uk/cru/projects/soap/pw/data/model/echo-g/soaparchive/erik/nc/slp/

Click here to see a listing of all files, and right-click each one that you want to download/save.

Note that the data files use the ECHO-G variable name instead of the variable name used on the SO&P website. Instead of slp__, the files are named slp.

Note also that the units used in the data files may be different to those given in the time series plots/data, because I converted some variables to more common units. Refer to the netCDF file headers for the units used (and any notes below regarding errors in this information).
For this variable, I multiplied the data files by 0.01 to convert the data to hPa.

Important notes regarding the slp__ variable:

Global-mean SLP should be a constant, unless the mass of the atmosphere is changing. ECHO-G does not conserve mass, so there is a gradual trend in global-mean SLP. Although it is small, users could remove it by subtracting a constant (equal to the change in global-mean SLP relative to the starting year or decade) from every grid box.
