Quick start

Accessing the data

The data is hosted on Microsoft Azure through their AI for Earth initiative. You can access the data in many ways, such as:

Point and click

Open the index file in your browser. You will see a list of links to datafiles which you can download by clicking on them in your browser.

Azure Blob libraries

There is a range of libraries in a range of languages for working with Azure Blobs. See the Azure Blob documentation for more info.

Automated downloading with AZCopy

There are lots of files, so we suggest installing azcopy command line tool, which you can download here. This lets you download whole directories or multiple files using wildcards to your computer of choice.

For example:
1. Download the file to the current directory:

azcopy cp "" .

  1. Download the contents of /metoffice_ukv_daily/snow_mean/ to ukv_daily_snow_mean/:

azcopy cp "*" ukv_daily_snow_mean/

  1. Download all the US state county averaged meteorology data which match the pattern us_55*.csv:

azcopy cp "" . --recursive --include-pattern "us_55*.csv"

How the data is organised

*Where possible, filenames are as described. However, given the short timeframes in which this data has been made available, minor variations in filename descriptions may occur.
