Whether Data Import

Allows to get weather data from Automated Surface Observing System (ASOS) stations (airports) in the whole world thanks to the Iowa Environment Mesonet website.

1. Parameters

1.1 Station ID

You can find Station ID from this site.

  1. Choose a network of the area where you want to get data and click "Switch to Network".
  2. Choose the characters of the station like "SFO" from the list.

Then type it to Station ID.

1.2 Date Start / Date End

You can limit the range of time with explicit dates like '2015-11-03' with these parameters.

2. Import

Once you concirmed the result, click Import button to import the data as a data frame in Exploratory.

3. Output

  • station - three or four character site identifier
  • valid - timestamp of the observation (UTC)
  • tmpf - Air Temperature in Fahrenheit, typically @ 2 meters
  • dwpf - Dew Point Temperature in Fahrenheit, typically @ 2 meters
  • relh - Relative Humidity in
  • drct - Wind Direction in degrees from north
  • sknt - Wind Speed in knots
  • p01i - One hour precipitation for the period from the observation time to the time of the previous hourly precipitation reset. This varies slightly by site. Values are in inches. This value may or may not contain frozen precipitation melted by some device on the sensor or estimated by some other means. Unfortunately, we do not know of an authoritative database denoting which station has which sensor.
  • alti - Pressure altimeter in inches
  • mslp - Sea Level Pressure in millibar
  • vsby - Visibility in miles
  • gust - Wind Gust in knots riem_networks 3
  • skyc1 - Sky Level 1 Coverage
  • skyc2 - Sky Level 2 Coverage
