    • RE: Satellite outage over the North and South America (Sep 28)

      @nilmar_20 O problema não é no satelite, ele ta operando normalmente, produzindo os dados.
      O problema é na infraestrutura de distribuição deles.
      Tem 3 principais formas de entregar esses dados:

      • GOES Rebrocast (GRB)
      • EUMETCast/GEONetCast
      • Open Data Dissemination Program Datasets

      Os dois primeiros metodos são transmissões via satelite, sendo o primeiro direto dos satelites meteorologicos e um conjunto de antenas em terra. O Segundo é um compilado de informações meteorologicas (modelos, radares, cartas, etc...), que tambem é transmitido por satelite, com diversos fornecedores diferente. Esses dois metodos estão funcionando, mas eles demandam e instalação de antenas e hardware especializado para coleta dessas informações.

      O terceiro sistema, distribui as informaçoes de satelite pela internet, usando os 3 principais provedores de cloud como hosts. É nesse sistema que a maioria dos usuarios, fora das universidades dependem para acesso aos dados.
      Este sistema é o que esta fora do ar. Por que o local de onde esses dados são enviados para internet foi bastante atingido pelo furacão Helen.

      English response:
      The problem is not with the satellite; it's operating normally and producing data. The issue lies with their distribution infrastructure.

      There are three main ways to deliver this data:

      • GOES Rebrocast (GRB)
      • EUMETCast/GEONetCast
      • Open Data Dissemination Program Datasets

      The first two methods are satellite transmissions: the first directly from weather satellites and a network of ground antennas. The second is a compilation of meteorological information (models, radars, maps, etc.), which is also transmitted by satellite, with various different providers. Both methods are functioning, but they require the installation of specialized antennas and hardware to collect this information.

      The third system distributes satellite data over the internet, using the three main cloud providers as hosts. This system, which most users outside of universities depend on to access the data, is the one that's down. The reason is that the location from which this data is uploaded to the internet was heavily impacted by Hurricane Helen.

      @BlSHOP Please explain why an who would pay a weather data company to sensor free data, that is not available on the sources?
      Go on and check by youself

      This are the links:
      NOAA Open Data Dissemination Program Datasets : https://www.noaa.gov/nodd/datasets
      AWS: https://registry.opendata.aws/noaa-goes/

      If you have found other source, please share it.

      This guives more context about the outage: https://github.com/awslabs/open-data-registry/pull/2386

      extracted from the commit:
      DATA FEED ISSUES - Due to major damage to critical infrastructure in the Asheville, NC area from Hurricane Helene, our GOES data feeds to the cloud have been impacted. We are working with local authorities and service providers in hopes that we can restore these feeds ASAP. Note that major celluar and network (fiber) infrastructure have been damaged and this may take time to adress. Thank you for your continued support.

      The only places that are receiving GOES data, are direct downloading, or taking it from someone who does it, from the satelite.
