Abstract

The aim of this study was to investigate climatological aspects (characterization) in seasonal potential evapotranspiration east of Acre, with the unit of study is the city of Rio Branco, capital of the State, considering a period of 34 years from 1980 to 2013, from monthly data from a weather station in a conventional surface. The methodology was adopted to realize the consistency of meteorological data in this way, first, was made the gap filling through the imputation of missing data in time series by means of Multivariate Time Series Data imputation and statistical tests of homogeneity of data (test or Run sequence) suggested by the World Meteorological Organization through its technical note 81 the indirect method Penmann-Montheith was used to calculate the potential Evapotranspiração. The results of this work through examination of the descriptive statistics showed that the average annual ETp is 3.54 mm d-1, with a very marked seasonality in June featuring a minimum of 2.93 mm d-1 and a maximum in October from 4.13 mm d-1 with an average annual accumulated 1290.99 mm and Standard Deviation of 53.41 mm and the months of June and August are what have higher variability and the interval from October to February the lowest variability.

Ethical Guidelines for Journal Publication

The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles. 

Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.

In particular, 

Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.

Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.

Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
