  1. GOES-16 RGB Training material: some case studies over South America Ester Ito, Natália Rudorff, Diego Souza, Douglas Uba, Silvia Garcia, Daniel Villa, Renato Negri CPTEC/ INPE Tokyo, Japan 7-9 November 2017

  2. Outline  Overview of the training material being developed at CPTEC/INPE as VLab activity  Examples of some case studies selected for the training course

  3. Training Material  Covers basics concepts related to atmospheric radiation and remote sensing follows the WMO guidelines for  training operational meteorologists

  4. Training program for 2017 ‘"Training Access and Use of JPSS and GOES-R Imagery for Environmental  Applications" 28, May, 2017, Santos, SP, Face to face course at the Brazilian Symposium of Remote Sensing "Training on GOES-16 for Operational Meteorological Services", 20 to  31/10/2017, internal, face to face for CPTEC's operational meteorologists "Training on GOES-16 for Operational Meteorological Services", online for  national and regional meteorological services - to be given by December 2017, (using MOODLE). Extra:   Curso Iberoamericano de Meteorologia Satelital "Aplicaciones de imágenes y productos de satélites a la meteorología de latitudes medias", Santa Cruz de la Sierra, Bolívia, 25 de Setembro a 6 de Outubro, 2017.

  5. The Centres of Excellence (CoE) for training in Satellite Meteorology DSA/CPTEC/INPE uses the platform for online training courses Moodle. The developing RGB training course will be available in this platform.

  6. Module 1: Introduction to GOES-R and the benefits of the next generation environmental satellite for weather monitoring and forecast Details about the new generation  geostationary meteorological satellites GOES-16 plataform: focus on ABI and GLM  sensors Spectral, spatial and temporal resolution of  ABI data Examples of images and derived products  from ABI GLM sensor: benefits and potential aplications  on nowcasting, weather monitoring References training material for GOES-16 and  operational meteorology

  7. Module 2: Module 2: Advanced Baseline Imager spectral channels and applications for operational meteorology  Material was translated to spanish

  8. Module 3: Multichannel RGB composits: examples for operational meteorology -WMO Recomended RGBs - Case studies for South America

  9. First, the basics of color composition are discussed R: red (vermelho) Also, some color blindness test are applied to the students G: green (verde) B: blue (azul) + = red green yellow + = green blue cyan + = blue red m agenta

  10. RGB Natural Color The first RGB presented is the Natural Color, easiest to understand and discuss the color composition (previous slide).
