Essay 1 – evaluation of data sources | Republic of Factistan

Name of site (linked to site), screenshot of home page

National Centers for Environmental Information

https://www.ncdc.noaa.gov/cdo-web

What is this site about?

It gives a detailed explanation of the climate in North America while giving you an easy way to navigate the site. You can go to the data sets and click on one of the options shown below and look at maps that give detailed data of everything from annual snowfall, to perspiration hourly. This is a great site to take a deeper look into the climate of North America throughout the past 30 years.

How to use the site:

  • This site is pretty self explanatory it is very easy to navigate and can help you find whatever you want to know about the climate over the past 30 years

What it has data about and time periods:

Daily Summaries

  • Global Historical Climate Network includes daily land surface observations from around the world.

Global Marine Data

  • Historical marine data are composed of ship, buoy, and platform observations from 1662-present. Data values are delayed by one month.

Global Summary of the Month

  • This data set gives a global summary of meteorological elements on a monthly time scale.

Global Summary of the Year

  • This data set gives a global summary of meteorological elements on a yearly time scale.

Local Climatological Data

  • Local Climatological Data is a monthly summary consisting of: 1) Summary sheet containing daily extremes and averages of temperature , departures from normal, average dew point and wet bulb temperatures, degree days, significant weather, precipitation, snowfall, snow depth, station and sea level pressure, and average and extreme wind speeds; 2) Hourly observations of most of these same weather elements plus sky conditions and visibility; 3) Hourly coded remarks; and 4) Hourly Precipitation table.

Normals Annual/Seasonal

  • Annual and Season climate normals are computed for the 30 year period from 1981 to 2010 for U.S. stations.

Normals Daily

  • Daily climate normals are computed for the 30 year period from 1981 to 2010 for U.S. stations. Values include temperature, degree days, precipitation, snowfall, frost/freeze dates, climate probabilities and statistics.

Normals Hourly

  • Hourly climate normals are computed for the 30 year period from 1981 to 2010 for U.S. stations (usually airports). Values include temperature, dew point temperature, sea level pressure, wind direction and speed, and other climate probabilities and statistics.

Normals Monthly

  • Monthly climate normals are computed for the 30 year period from 1981 to 2010 for U.S. stations. Values include temperature, degree days, precipitation, snowfall, snow depth, and many other climate probabilities and statistics.

Precipitation 15 Minute

  • This dataset contains historical 15-minute precipitation observations for selected U.S. stations. Data values are typically delayed six months or more.

Precipitation Hourly

  • This dataset contains historical hourly precipitation observations for selected U.S. stations. Data values are typically delayed six months or more.

Weather Radar (Level II)

  • Level-II NEXRAD data include three meteorological base data quantities: reflectivity, mean radial velocity, and spectrum width. With the advent of dual polarization beginning in 2011, additional base products of differential reflectivity, correlation coefficient and differential phase are available

Weather Radar (Level III)

  • Level-III NEXRAD data are 40+ products generated from NEXRAD Level-II data using computer algorithms at the radar sites and include base and composite reflectivity, precipitation estimates, storm relative velocity, vertical integrated liquid, hail index, tornadic vortex signature, mesocyclone identification, and echo tops along with the dual-polarization measurements of differential reflectivity, correlation coefficient and specific differential phase, hydrometer classification, and melting layer data.

What geographical area it covers: 

  • It covers North America

For which of Factistan’s issues it has relevant data:

  • It covers climate change and that is a huge issue that Factistan wants to cover.

Who collected it: organization; url of web site’s About page:

  • NCEI is responsible for hosting and providing access to one of the most significant archives on Earth, with comprehensive oceanic, atmospheric, and geophysical data. From the depths of the ocean to the surface of the sun and from million-year-old sediment records to near real-time satellite images, NCEI is the Nation’s leading authority for environmental information.

How they collected it: primary research, surveys, reports from other data collection agencies

  • They have set up multiple stations around North America that track weather and log the data into one huge server. Which would be primary research

How they present it: data sets (spreadsheets), tables, visualizations (charts and graphs), maps

  • They use maps and data sets to present their data.

How to cite the data source: MLA, APA, HTML (exposed URL)
