Getting Data

• US Landsat 4-8 ARD: Provisional Surface Temperature (ST)

  1. Make an account at (https://earthexplorer.usgs.gov/)
  2. Install Bulk Download Application
  3. On Earth Exloper site search panel, select desired criteria:
     • Date Range: 2014 to 2020
     • Datasets: US Landsat 4-8 ARD
     • Tile grid horizontal: 29 (NYC)
     • Tile grid vertical: 7 (NYC)
       • search for tile grid here
  4. Follow BIG DATA Download instructions from the blog site (blogs.fu-berlin.de)
     • Where the instructions say "Choose “Non-Limited Results” and “CSV” in order to export the metadata of every single file found to a csv-file (which is a text file)" choose "Comma (,) Delimited" format instead.

• Ground Monitor Temperature:

  1. Select your local stations. (Central Park, LaGuardia, Kennedy) Local Climatological Data (LCD)
  2. You need to add the data to your cart, then go to your cart, where you can select that you want a csv and subset to the dates you are interested in.
     • Central Park

Validating Data

• Satellite Readings
  1. Cloud Cover: https://landsat.usgs.gov/landsat-8-cloud-cover-assessment-validation-data#Urban
  2. Comparing Ground Monitor temperatures to Satellite readings
