Claim:
1. A method for providing a warning of radiation-dose-relevant space-weather events at cruising altitudes, said method comprising the following steps: acquiring radiation data of ionizing radiation in earth's atmosphere via at least one of satellite-based, air-based and ground-based measurement instruments, providing a radiation model for a 3D-spatially resolved estimation of a radiation field at cruising altitudes of the earth's atmosphere by use of a radiation dose rate scale that is based on a continuous range of values, generating 3D-spatially resolved rates of an estimated radiation dose that is based upon a calculation of the acquired radiation data with the radiation model, wherein the estimated radiation dose that is calculated has an estimated radiation dose rate scale that is based on a continuous range of values, dividing the estimated radiation dose rate scale, which is based on a continuous range of values, into a graduated estimated radiation dose rate scale, the graduated dose rate scale comprising discrete successive ranges of values of estimated radiation dose rates, wherein the discrete successive ranges of values continuously increase by a predetermined multiple, such that a first range of values is between an estimated radiation dose rate of zero and a presettable first upper limit, a second range of values is between the first upper limit and a second upper limit which is equal to the predetermined multiple of the first upper limit, and each further range of values is between the upper limit of the next smaller range of values and an upper limit which is equal to the predetermined multiple of the upper limit of the next smaller range of values, and wherein the predetermined multiple is a natural number that is greater than one, assigning respectively a different index value to each successive range of values of the graduated estimated radiation dose rate scale, wherein the different index values successively increase and are respectively assigned to correspond with the successively increasing ranges of values of the graduated dose rate scale, and mapping the assigned index values to a grid model of earth's atmosphere, and indicating the mapped index values on the grid model to provide a warning that indicates the index value associated with the range of values within which is situated the estimated radiation dose rate for a predefined region in the earth's atmosphere.
