Service Consumption Constraint

Usage is limited as per our throttling standard policies:

  • For the VAAC London QVA Gridded Data API - 1,5000 individual requests per day.
  • For the VAAC London QVA Products API - 500 individual requests per day.

However, it is possible to download all data published for an individual volcano by making only four requests:

  • One request to find out the volcano number from the collections information
  • One request for all deterministic gridded data
  • One request for all probabilistic gridded data
  • One request for all IWXXM data
