Except for cloud area fraction, this data must be provided on pressure levels, including at least the following standard levels, , , , , , , , , , , , 70, 50, 30, 20, 10 hPa. Table O1a: Monthly-mean 1-d ocean data latitude, region, time:month. Zonal mean over all oceans and also zonal mean for individual ocean basins Atlantic, Indian, and Pacific basins: divide roughly at 20E and E.
Table O1b: Monthly-mean 2-d ocean data latitude, depth, region, time:month. Data must be provided on depth levels. We recommend that these match the 33 standard levels of Levitus observations: 0, 10, 20, 30, 50, 75, , , , , , , , , , , , , , , , , , , , , , , , , , , and meters. Note that the units do not include mass. This should include only the explicitly calculated, purely advective component and should exclude contributions of the 'bolus velocity' that arise, for example, in the Gent-McWilliams parameterization.
Table O1c: Monthly-mean 0-d or 2-d ocean or sea ice data longitude, latitude, time:month. As defined here, "the geoid" is a surface of constant geopotential that, if the ocean were at rest, would coincide with mean sea level.
Report zos as "missing" over grid cells that are entirely land. There are a couple of acceptable options for reporting this field: 1 if the geoid is defined to relate to the instantaneous volume of the ocean, the global mean of zos will always be zero, and 2 if the geoid is defined relative to a time-mean sea level over some period, then the global mean of zos will be time-dependent.
In either case a global mean time-series of sea level should also be reported as described in the next two table entries immediately below. In general IPCC analysis of global mean sea level changes will not rely on zos.
It is recommended that in reporting zos, the atmospheric "inverted barometer" effect be omitted, since it can be easily calculated from the reported mean sea level pressure field. The "comment" attribute associated with zos should indicate whether or not the atmospheric "inverted barometer" influence on zos has been included. Additionally, it should be noted in the "comment" attribute whether zos is obtained directly, as in a free-surface model, or has been derived, for example, from geostrophy using diagnosed velocities at some level or from geostrophy relative to an assumed level of quiescence.
The fixed reference height should be invariant across all IPCC simulations by a model. In a rigid-lid model this quantity can be calculated by using a reference 3D salinity field to compute density as the 3D temperature field evolves.
Please note in the "comment" attribute any assumptions or methodological details related to calculation of this time-series. Note that to good approximation the difference between zostoga and zosga yields the global mean change in sea level due to water budget imbalances presumably, resulting largely from changes in glacial mass. Thus, for time means, compute as the weighted sum of thickness averaged over the sea ice-covered portion of the grid cell divided by the sum of the weights, with the weights equal to the area covered by sea-ice; Report as 0.
Table O1d: Time-independent 2-d ocean data longitude, latitude. Report here the sea floor depth for present day. It should be computed as the total qflux energy added to the ocean-portion of the grid cell divided by the ocean area in the grid cell; report as "missing" or 0.
Report only for slab ocean experiments. Table O1e: Monthly-mean 3-d ocean data longitude, latitude, depth, time:month.
For the 3-d ocean fields, it is likely that storage space constraints will limit relatively quick access to output from only a single member of each ensemble, so in prioritizing your processing, consider initially sending PCMDI the 3-d ocean output from only 1 member of the ensemble. Table A2a: Daily-mean 2-d atmosphere data longitude, latitude, time:day. It is recommended that the daily means be computed for intervals beginning at 0 Z and ending the following midnight at 0Z.
Except for the temperature mean, min. Also report data only for the years specified in the table at the end of this document. The CMOR singleton dimension default value of 2 m can be overridden, if absolutely necessary, by redefining axis "height1". The CMOR singleton dimension default value of 10 m can be overridden, if absolutely necessary, by redefining axis "height2". Table A2b: Daily-mean 3-d atmosphere data longitude, latitude, pressure, time:day.
This data should be provided for just one ensemble member per scenario, and for only the years specified in the table at the end of this document. Also this data must be provided on pressure levels, including at least the following subset of standard levels, , , , , , , , hPa.
Table A3: 3-bourly 2-d atmosphere data longitude, latitude, time:3hour at 0, 3, 6, 9, 12, 15, 18, 21 Z. The data should be provided for just one ensemble member per scenario, and for the years specified in the table at the end of this document.
Frich et al. Table A4: Extremes indices longitude, latitude, time:year from Frich et al. The VOC list was expanded with the December update. This file has one record per year per CBSA or county. These have one record per day per CBSA or county. For reference, there is also a file listing all of the files on this page and the date they were modified.
