EKF400 is a monthly resolved paleo-reanalysis covering the period 1603 to 2003. Early instrumental temperature and surface pressure observations, temperature indices derived from historical documents and temperature and moisture sensitive tree-ring measurements were assimilated into an atmospheric general circulation model ensemble using a Kalman filtering technique. This data set combines the advantage of traditional reconstruction methods of being as close as possible to observations with the advantage of climate models of being physically consistent and having 3-dimensional information about the state of the atmosphere for various variables and at all points in time.

Geopotential height is the geopotential divided by the standard acceleration due to gravity. It is numerically similar to the altitude (or geometric height) and not to the quantity with standard name height, which is relative to the surface. [CF-Standard Name]; unit: m air_pressure_at_sea_level sea_level means mean sea level, which is close to the geoid in sea areas. Air pressure at sea level is the quantity often abbreviated as MSLP or PMSL.[CF-Standard Name]; unit: Pa level_temp not filled; unit: m and Pa longitude longitude [CF-Standard Name]; unit: degrees_east precipitation_amount "Amount" means mass per unit area. "Precipitation" in the earths atmosphere means precipitation of water in all phases. [CF-Standard Name]; unit: kg m-2 lagrangian_tendency_of_air_pressure "tendency_of_X" means derivative of X with respect to time. The Lagrangian tendency of a quantity is its rate of change following the motion of the fluid, also called the "material derivative" or "convective derivative". The Lagrangian tendency of air pressure, often called "omega", plays the role of the upward component of air velocity when air pressure is being used as the vertical coordinate. If the vertical air velocity is upwards, it is negative when expressed as a tendency of air pressure; downwards is positive.[CF-Standard Name]; unit: Pa s-1 air_temperature Air temperature is the bulk temperature of the air, not the surface (skin) temperature. [CF-Standard Name]; unit: K pressure_level_gph not filled; unit: Pa time time [CF-Standard Name]; unit: not filled northward_wind "Northward" indicates a vector component which is positive when directed northward (negative southward). Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.) [CF-Standard Name]; unit: m s-1 eastward_wind "Eastward" indicates a vector component which is positive when directed eastward (negative westward). Wind is defined as a two-dimensional (horizontal) air velocity vector, with no vertical component. (Vertical motion in the atmosphere has the standard name upward_air_velocity.)
