The golf green cover is made of three layers; a water-impermeable top layer and intermediate and bottom layers made of semi-rigid insulating foam. The bottom layer has perforations therein. Transversal air passages are formed between the intermediate and the bottom layers and communicate with the perforations. Each transversal air passage has a cord segment and an arc segment whereby it is non-collapsible under snow loads. Longitudinal air passages are formed under the seams between adjacent cover panels and communicate with the transversal air passages. A gas collection pipe is mounted in one of the longitudinal air passages and communicates with an air valve and a rotary ventilator. The perforations, the air passages, the air valve and the ventilator are usable to evacuate gases accumulating under the cover and to periodically aerate the covered grass. A thermocouple is bonded to the underside surface of the bottom layer and is usable as a learning tool to develop knowledge of the conditions of a covered golf green.
