4th NOAA Workshop on Leveraging AI in Environmental Sciences
+
+Título: 4th NOAA Workshop on Leveraging AI in Environmental SciencesResumo: The interactive workshop will be a virtual event to build collaboration and initiate the active development of AI-powered applications and community standards. We invite developers, data scientists, domain experts, social scientists, and downstream users to form small teams around different use cases that are relevant to three themes relevant to NOAA Mission Areas: Fire Weather and Impacts: Fire weather sits at the intersection between terrestrial ecosystems, atmospheric systems, and society. The impacts of fire weather on communities in or near the path of fire progression can be disastrous both in the short and long term. How can we leverage AI and rich environmental data to develop solutions to help diverse stakeholders to better quantify and manage the impact of fire weather? AI for Ocean Conservation: The ocean plays a crucial role in climate and the world’s sustainable development goals. AI has demonstrated great potential in ocean conservation, such as identifying wildlife, detecting marine debris, and monitoring illegal fishing. How can we proliferate AI development for ocean conservation by reducing the barrier of using state-of-the-art AI tools? Interoperable Digital Twin Earth: Digital Twin Earth (DTE) is a digital representation of the complex Earth system that allows us to visualize, monitor, and forecast natural and human activity on the planet. As different agencies and organizations, including NOAA, NASA, ECMWF, and UK Met Office, start to develop various DTE systems, how can we develop an international standard to ensure digital twins are interoperable and easily integrated into other digital twin systems for different socioeconomic sectors?

+Título: MONAN: Um novo paradigma de foco e organização para o avanço da previsão numérica de tempo, clima e ambiente no BrasilResumo: Prever o clima em diversas escalas é um dos maiores desafios técnico-científicos enfrentados pela humanidade. As principais razões das dificuldades residem principalmente na intrínseca natureza caótica da atmosfera e suas interfaces, o sistema de equações diferenciais que governa a dinâmica da atmosfera não admite solução analítica (requer solução aproximada em supercomputadores) e impraticabilidade de caracterizar o estado da atmosfera e suas interfaces com exatidão. No entanto, com investimento e muita pesquisa, diversos centros internacionais vem avançando na qualidade da previsão numérica da atmosfera aumentando sua acurácia, prazos de previsibilidade e usabilidade. Neste seminário, serão discutidos os elementos básicos da previsão numérica de tempo e desafios atuais para o seu contínuo aprimoramento. Se dará ênfase na apresentação do programa MONAN (Model for Ocean-laNd-Atmosphere predictioN).

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n * Observable.\n * @param {Function} error (optional) A handler for a terminal event resulting from an error.
