 ===== Boundary conditions =====
+==== Summary of 6ka boundary conditions ====
+^      ^   PMIP3  ^  Alternative solution  ^
+|  Orbital parameters  |  [ **ecc** = 0.018682 ] - [ **obl** = 24.105° ] - [ **peri-180°** = 0.87° ]  | |
+|  Date of vernal equinox  |  March 21 at noon  | |
+|  Trace gases  |  [ **CO<sub>2</sub>** = 280 ppm ] - [ **CH<sub>4</sub>** = 650 ppb ] - [ **N<sub>2</sub>O** = 270 ppb ] - [ **CFC** = 0 ] - [ **O<sub>3</sub>** = same as PI ]  | |
+|  Aerosols  |  Same as PI  | |
+|    | |  |
+|  Solar constant  |  1365W/m<sup>2</sup>  |  As in PI  |
+|  Vegetation     |  Interactive  |  See specific note below  |
+|  Ice sheets      |  Remnant Laurentide ice-sheet (provided)  |  Same as PI  |
+|  Topography and coastlines  |  Modification of Hudson Bay coastlines (provided)  |  Same as PI  |
+Please use the [[index#page_bottom_tag|discussion]] panel to **comment** this table!
+==== Vegetation ====
+Depending on the complexity of the model used the vegetation will be either \\
+- computed by the model \\
+- prescribed to PI (some ESM may only compute vegetation phenology and carbon cycle)\\
+- prescribed to 6ka vegetation reconstructed from a combination of model output and data analyses (please use the map provided here) \\
+- Obtained from asynchronous coupling with a DVGM ([[http://pmip2.lsce.ipsl.fr/synth/biome4.shtml|Biome 4 model]] provided)
+==== For Earth System Models with interactive carbone cycle ====
+The simulations are forced by CO2 concentrations. Please use the same protocol as in CMIP5 to store the carbone fluxes and the variables needed for PCMIP (see list here)
+==== Insolation ====
+Note that insolation should follows PMIP requirements. Please check it carefully using the following tables ([[http://pmip2.lsce.ipsl.fr/design/tables/inso_tables_6k.shtml|6ka BP insolation tables]])
 ===== Initial conditions =====
+^  ^  PMIP3  ^  Alternative solution  ^
+| Initial conditions |  Branch off PI after adjustement  |  Same as in PI  |
+| Model spin up      |  Same as in PI  |  |
