Abstract:
The joint Nordic calculation method Nord2000 is to be used for i.e. noise mapping. It prescribes that nine meteo-classes are used as basis for the year average of the parameters Lden and Lnight. This has shown to result in excessive calculation times. This report recommends the se of only four meteo-classes in connection with noise mapping and similar tasks, where the calculation time is important, and it defines the four classes. For noise mapping in cities only one meteo-class is needed.

Abstract in Danish:
Beregningsmetoden Nord2000, som skal bruges bl.a. til støjkortlægning af veje og jernbaner, benytter 9 vejrklasser som grundlag for at fastlægge årsmiddelværdien af støjniveauet, udtrykt ved Lden og Lnight. Dette medfører ¹ netop ved støjkortlægning ¹ upraktisk lange regnetider. Rapporten anbefaler, at der til støjkortlægning og andre store opgaver, hvor regnetiden er væsentlig, benyttes 4 vejrklasser, som defineres nærmere. Ved støjkortlægning i byer kan én vejrklasse være tilstrækkelig.
