NOAA Integrated Surface Data (ISD)

Weather ISD NOAA

Verdensomspændende vejrhistorikdata hver time (eksempel: temperatur, nedbør og vind) fra NOAA (National Oceanic and Atmospheric Administration).

ISD-datasættet (Integrated Surface Dataset) består af verdensomspændende vejrobservationer ved jordens overflade fra over 35.000 stationer, hvor den bedste spatiale dækning er tydeligst i Nordamerika, Europa, Australien og dele af Asien. Parametre omfatter: luftkvalitet, atmosfærisk tryk, atmosfærisk temperatur/dugpunkt, atmosfæriske vinde, skyer, nedbør, havbølger, tidevand med mere. ISD refererer til dataene i den digitale database samt det format, som den timevise, synoptiske (3-timers) daglige vejrobservation er lagret i.

Mængde og opbevaring

Dette datasæt gemmes i Parquet-formatet. Det opdateres dagligt og indeholder omkring 400.000.000 rækker (20 GB) i alt fra og med 2019.

Dette datasæt indeholder historiske poster, der er akkumuleret fra 2008 og frem til i dag. Du kan bruge parameterindstillingerne i vores SDK til at hente data inden for en bestemt tidsperiode.

Lagerplacering

Dette datasæt er gemt i Azure-området Det østlige USA. Tildeling af beregningsressourcer i det østlige USA anbefales af tilhørsmæssige årsager.

Yderligere oplysninger

Dette datasæt stammer fra NOAA Integrated Surface Database. Du kan få yderligere oplysninger om datasættet her og her. Send en mail til , hvis du har nogle spørgsmål til datakilden.

Urban Heat Islands

From the Urban Innovation Initiative at Microsoft Research, data processing and analytics scripts for hourly NOAA weather station data that produce daily urban heat island indices for hundreds of U.S. cities, January 1, 2008 - present, including automated daily updating. Urban heat island effects are then examined over time and across cities, as well as aligned with population density.
