Content Description
  Content Summary: The CPC Realtime Analysis is prepared using GTS daily reports and additional reports provided by CPTEC, INMET, FUNCEME and SIMEPAR of Brazil and INAMHI of Ecuador. The primary sources of daily precipitation data for Brazil used in the historical gridded precipitation analyses (2005 version) are: a) Agencia Nacional de Energia Eletrica (National Agency for Electrical Energy ANEEL) (1960-1997), b) Agencia Nacional de Aguas (National Water Agency ANA) (1948-2004), c) Fundacao Cearense de Meteorologia e Recursos Hidricos (Meteorology and Hydrologic Resources Foundation of Ceara (FUNCEME) (1973-2004), d) Superintendencia do Desenvolvimento do Nordeste (Superintendence for Development of the Northeast) (SUDENE) (1948-1998), e) Departamento de Aguas e Energia Eletrica do Estado de Sao Paulo (Department of Water and Electrical Energy of Sao Paulo DAEE) (1948-1997) in collaboration with the Centro de Previsao de Tempo e Estudos Climaticos (Brazilian Weather Forecast and Climate Studies) (CPTEC), and f) Technological Institute of Parana (SIMEPAR) (1997-2004).

Analysis Scheme: Modified Cressman (1959) Scheme (Glahn et al. 1985; Charba et al. 1992). Minimum stations for analysis: 250 for precipitation. If the number of stations is less than the minimum, then the analysis is not performed for that day.

  Content Purpose: Real-time Monitoring.
