This data set provides Daymet Version 3 model output as gridded estimates of daily weather parameters for North America and Hawaii: including Canada, Mexico, the United States America, Puerto Rico, Bermuda. The island areas Hawaii Rico are available files separate from continental land mass. variables include following parameters: minimum temperature, maximum precipitation, shortwave radiation, vapor pressure, snow water equivalent, day length. covers period January 1, 1980 to December 31...
More information: http://daymet.ornl.gov Presenter: Ranjeet Devarakonda Environmental Sciences Division Oak Ridge National Laboratory (ORNL) Daymet: Daily Surface Weather Data and Climatological Summaries provides gridded estimates of daily weather parameters for North America, including continuous surfaces minimum maximum temperature, precipitation occurrence amount, humidity, shortwave radiation, snow water equivalent, day length. The current data product (Version 2) covers the period...
Abstract Data standardization combined with descriptive metadata facilitate data reuse, which is the ultimate goal of Findable, Accessible, Interoperable, and Reusable (FAIR) principles. Community or standards are increasingly created through an approach that emphasizes collaboration between various stakeholders. Such requires platforms for on development process centers sharing information receiving feedback. Our objective in this study was to conduct a systematic review identify reporting...
Web application technologies are growing rapidly with continuous innovation and improvements. This paper focuses on the popular Spring Boot [1] java-based framework for building web enterprise applications how it provides flexibility service-oriented architecture (SOA). One challenge any Spring-based is its level of complexity configurations. makes easy to create deploy stand-alone, production-grade very little configuration. Example, if we consider Model-View-Controller (MVC) [2], need...
Atmospheric Radiation Measurement (ARM) is a multi-laboratory/multi-institutional, US Department of Energy Office Science National User Facility. ARM's data currently hosted at the ARM Data Center (ADC) in Oak Ridge, Tennessee. The ADC holds more than 12,000 products, with total holding 1.8 PB that dates back to 1992. This includes from instruments, value-added model outputs, field campaigns, and principle investigator contributed data. In this paper, we discuss how big federal scientific...
In this paper we present how research projects at Oak Ridge National Laboratory - Distributed Active Archive Center (ORNL DAAC) are using the Drupal content management system (CMS) for creating collaborative environments scientists. We will discuss scientific data and documents stored represented in they can be shared with scientists other organizations.
Scientific datasets are continuously growing with the amount of raw data being collected worldwide. This poses biggest challenge to web search engines on how retrieve them efficiently. paper discusses major scientific centers using popular open-source platforms such as Solr [1] structured stored in sources relational database management systems its import handler mechanisms [2]. Additionally, we will also focus can configure serve advanced full-text, faceted capabilities, along key features,...
In this paper, we will discuss how NASA's Oak Ridge National Laboratory Distributed Active Archive Center (ORNL DAAC) is distributing large volumes of `structured' data using Daily Surface Weather Data and a corresponding Climatological Summaries Dataset (Daymet) as an example.
One of the challenges in supplying communities with wider access to scientific databases is need for knowledge database languages like Structured Query Language (SQL). Although SQL language has been published many forms, not everybody able write queries. Another challenge that it might be practical make public aware structure databases. There a novice users query relational using their natural language. To solve this problem, interfaces structured have developed. The goal provide more...
The Atmospheric Radiation Measurement (ARM) Climate Research Facility (www.arm.gov) provides atmospheric observations from diverse climatic regimes around the world. Currently, ARM archives over 22 million user assessable data files, primarily stored in NetCDF file format, with total volumes close to one Petabyte. In this paper, we will discuss how is currently storing, distributing, cataloging and visualizing such large of multi-dimensional climate model also describe their future plan.
Data quality assessment, management and improvement is an integral part of any big data intensive scientific research to ensure accurate, reliable, reproducible discoveries. The task maintaining the data, however, non-trivial poses a challenge for program like Department Energy's Atmospheric Radiation Measurement (ARM) that collects from hundreds instruments across world, distributes thousands streaming products are continuously produced in near-real-time archive 1.7 Petabyte size growing....
The next-generation On-line Metadata Editor (OME) is an easy-to-use tool to help document scientific data in a well-structured popular metadata format. In this paper, we discuss the newest that Oak Ridge National Laboratory has developed input, edit, and manage how it helping intensive science centers across many federal agencies prepare make their BigData discoverable.
In this paper we present how research projects at Oak Ridge National Laboratory are using Semantic Search capabilities to help scientists perform their research. We will discuss the Mercury metadata search system, with of semantic capability, is being used find, retrieve, and link climate change data.
Several factors must be considered in designing a highly accurate, reliable, scalable, and user-friendly geospatial data search interfaces. This paper examines four critical questions that ought to during design phase: (1) Is the interface or API provides capability useable by both humans machines? (2) Are results consistent reliable? (3) output response format free use, community-defined, non-propriety? (4) Does clearly state usage clauses? discusses how certain repositories at US...
Storing data is easy, but finding and using not. It desirable that the stored in a structured format, which can be preserved retrieved future. Creating Metadata for one way of creating formats. provide Multidisciplinary access will foster more robust scientific discoveries. In recent years, there has been significant advancement areas management retrieval techniques, particularly terms standards protocols archiving metadata. New search technologies are being implemented around these...
Information connectivity and retrieval has a role in our daily lives. The most pervasive source of online information is databases. amount data growing at rapid rate database technology improving having profound effect. Almost all applications are storing retrieving from One challenge supplying the public with wider access to informational databases need for knowledge languages like Structured Query Language (SQL).
