This letter is intended to open discussions with the Universidade Federal do Rio de Janeiro on the possibility of becoming a top level relay node for Brazilian universities that would like to participate in the Unidata IDD. What I have in mind is creating an IDD-Brazil where the UFRJ plays a pivotal role. Unidata is currently providing data in near-realtime to two different universities in Brazil: Universidade Federal do Rio de Janeiro, and Universidade Federal do Para. Dr. Jose Ricardo Santos de Souza (Ricardo) <address@hidden> of the UFPA has relayed to us interest by other Brazilian universities in data available through the IDD. In working with Ricardo, I have had the chance to become well familiar with the capabilities of the Brazilian national network, RNP. It seems that the network Point of Presence (POP) for Brazil that is closest electronically to IDD relay nodes in the United States is in Rio De Janerio. This makes the UFRJ the logical choice for the main relay point for IDD access for other Brazilian universities. The network connections from the US to Rio are literally twice as fast (in terms of latency) as the connection to the UFPA in Belem, for example. I have had great success in the past couple of months in setting up the UFPA to receive a variety of data available in the IDD: satellite imagery from both GOES-East and GOES-West, all of the observational data available from the Global Telecommunications System (GTS), and all of the global model data available in the NOAAPORT broadcast generated by the US National Weather Service. In the coming weeks, we will be adding a satellite sector focused on Brazil to the set of satellite imagery we are already shipping in the IDD. We also have plans for attempting to ship some high resolution model output (the 1 degree global AVN initializations, for instance) to the UFPA. The high resolution model data would be easier to send to UFRJ and then relay it to UFPA, so your participation as a toplevel relay node would be most helpful in this endeavor. Do you think that the UFRJ would be willing to act as the top level IDD relay node for Brazilian universities? If yes, we are willing to help you tune your LDM installation and set it up for relaying. Again, if you are not the appropriate person to discuss expanding IDD participation at UFRJ, please pass along this note to the appropriate person. Thank you for your time. Tom Yoksas
