Operational hydrology report (OHR), 21. Methods of correction for systematic error in point precipitation measurement for operational use
This publication, in the form of an operational manual, describes methods of correcting errors with diagrams, formulae, a detailed chronology and over 100 references. The long-term aim is the wider acceptance and use of internationally recognized methods of correcting precipitation data.Published by: WMO ; 1982

Evaporation losses from containers of hellmann precipitation gauges
The evaporation losses from the container of an old galvanized Hellmann gauge, 7·1 cm2 aperture area, were five times greater than the losses from the container of a new gauge, 1·8 cm2 aperture area, of almost the same grey colour. The maximum evaporation from the old gauge amounted to 0·75 mm per day. The same evaporation losses in the Baye of Montreux basin over a period of 10 years from April to September amounted to 0·09 mm per measurement or to 0·7 per cent of the precipitation catch. There is a relationship between the monthly percentage evaporation losses and the ratio of evaporation ti ...PermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalinkPermalink
