O Instituto Nacional de Pesquisas Espaciais (INPE) monitora fluxos da Radiacao Ultravioleta (R-UV), em solo, desde 1990, atraves de uma rede de espectrofotometros  Brewer  no Brasil, Bolivia, Chile e Antartida. O espectrofotometro e reconhecido pela Organizacao Mundial de Meteorologia (OMM) e pelo programa “ Global Atmosphere Watch ” (GAW) como padrao para medicoes de ozonio e R-UV. O objetivo deste trabalho e descrever e avaliar o funcionamento do instrumento no processo de coleta da R-UV, ao mesmo tempo em que apresenta metodologia desenvolvida para validacao de dados referentes ao periodo de 1997 a 2012 nas cidades de La Paz, Bolivia e Natal, Brasil. Avaliou-se o funcionamento da parte optica com destaque nas Lâmpadas Padrao (SL) dos espectrofotometros. Observaram-se desgastes naturais no funcionamento dos instrumentos. Utilizou-se o modelo matematico de transferencia radiativa TUV “ Tropospherical Ultraviolet Visible Model ” para simular uma base de dados do indice de radiacao ultravioleta (IUV). Por meio de analise de regressao linear entre as duas bases, realizou-se o ajuste da serie temporal do  Brewer  (variavel preditora) por meio da serie temporal do TUV (variavel resposta). Este  review  apresenta algoritmo para validacao dos registros e um roteiro para a pre-analise dos dados coletados. A B S T R A C T The National Institute for Space Research monitors the fluxes of Ultraviolet Radiation (R-UV) on ground, since 1990, through a network of Brewer Spectrophotometers in Brazil, Bolivia, Chile and Antarctica. The spectrophotometer is recognized by the World Meteorological Organization (WMO) and the program Global Atmosphere Watch (GAW) as the standard for ozone and R-UV measurements. The objective of this work is to describe and evaluate the operation of the Brewer in the process of collecting R-UV, at the same time that it presents methodology developed for data validation for the period from 1997 to 2012 in the cities of La Paz, Bolivia and Natal, Brazil. Evaluation the operation of the optical part with highlight in the Standard Lamps (SL) of Spectrophotometers. Natural wear in the operation of the instruments were observed. The mathematical model of radiative transference of the Tropospherical Ultraviolet Visible Model (TUV) to simulate an IUV database. By means of linear regression analysis between the two bases, the time series of the Brewer (predictor variable) was adjusted by means of the TUV time series (response variable). This review presents an algorithm for validation of its records and a routine for the pre-analysis of the collected data.
