1. A radiation shield for weather sensors comprising in combination:

  • a housing defining an internal vertical flow path for aspirated air;

    the housing defining a volume for the placement of at least one weather sensor;

    a plurality of radiation deflecting surfaces surrounding the housing, the radiation-deflecting surfaces having flow apertures defined therein to permit passage of convention currents through the radiation deflecting surfaces independent of the internal vertical flow path;

    a powered fan mounted at one end of the housing for drawing air from the other end of the housing to the fan and then out of the vertical flow path; and

    , a support for supporting a weather measuring sensor in the vertical flow path away from the fan whereby atmosphere drawn by the fan into the vertical flow path passes over the weather sensor to enable measurement of parameters of the passing air.
