Jeffrey, S.J., Carter, J.O., Moodie, K.B. and Beswick, A.R. (2001). Using spatial interpolation to construct a comprehensive archive of Australian climate data, Environmental Modelling and Software, Vol 16/4, pp 309-330. DOI: 10.1016/S1364-8152(01)00008-1. Available online here.

This is the Patched Point Dataset and Data Drill primary reference. This article describes the interpolations of daily rainfall, temperature, radiation, evaporation and vapour pressure that have been used in the Data Drill and the Patched Point Dataset. An estimation of expected errors is included. An update describes the reduction in errors achieved by interpolation improvements. This is the primary reference for SILO. The paper describes the algorithms used in preparing SILO datasets, including a detailed analysis of the expected accuracy of the interpolated estimates. An update describes the reduction in errors achieved by modifications to the interpolation algorithm.

This is the original paper for the calculation of FAO56 reference evapotranspiration.

Chiew and McMahon compared Morton's wet environment evapotranspiration with Penman's potential evapotranspiration. The estimates are similar in wet conditions, but Morton's estimate is lower than Penman's in dry conditions.

This paper shows that Morton's method has several deficiencies: 1) The use of a water transfer coefficient that is not dependent on wind results in overestimation in low wind conditions, and underestimation in high wind conditions; and 2) The calculation of albedo may lead to significant errors. It also shows that Morton's method may not be sufficiently accurate over short accumulation periods (e.g. 24 hours).
