Evapotranspiration: A scientometric analysis

This study shows how the advent of technologies and the increase of study centers have influenced evapotranspi­ration estimation methods in different regions of Brazil and worldwide. Therefore, a search was performed, based on Scopus database, on papers containing the word “evapotranspiration” in the title, abstract, and/or keywords. We evaluated the first year of publication available on the platform, the authors of the first publications, the name of the journal in which the work was published, and the country of publication. Then, a new search was performed on papers containing the words “evapotranspiration” AND “estimate” *OR “method” in the title, abstract, and/or keywords. The following were evaluated in each article: i) year of publication; ii) type of study; iii) name of the jour­nal in which the study was published; iv) Qualis CAPES of journals; v) concentration area; vi) keywords; vii) lan­guage of origin; viii) country of publication; and ix) estimation method used in Brazil. The FAO-56 standard method is the most widely used, however, remote sensing has been increasingly used in studies.
