Pressure levels collection Met Office UKV 2km deterministic forecast

This collection offers 7 parameters at 33 available pressure levels (from 100000Pa to 1000Pa) from the Met Office UKV 2km deterministic forecast. This is a high-resolution gridded weather forecast for the UK, with a resolution of 0.018 degrees, projected on to a 2km horizontal grid.

The data is available as NetCDF files. It's offered on a free, unsupported basis, so we don't recommend using it for any critical business purposes.

## Pressure Levels
Available pressure levels, in Pascals (Pa), are:
* 100000.0 97500.0 95000.0 92500.0 90000.0 85000.0 80000.0 75000.0 70000.0 65000.0 60000.0 55000.0 50000.0 45000.0 40000.0 37500.0 35000.0 32500.0 30000.0 27500.0 25000.0 22500.0 20000.0 17500.0 15000.0 12500.0 10000.0 7000.0 5000.0 4000.0 3000.0 2000.0 1000.0
Exceptions:
* Wet bulb potential temperature on pressure levels (wet_bulb_potential_temperature_on_pressure_levels) available pressure levels, in Pascals (Pa), are 85000.0 70000.0 50000.0

## Coverage area
The forecast covers the UK and Ireland, with the following latitude and longitude coordinates for each corner of the included area:
* Southwest: 48.8643°N, 10.6734°W 
* Northwest: 61.3322°N, 13.7254°W 
* Northeast: 61.6102°N, 4.3408°E 
* Southeast: 49.0594°N, 2.4654°E 

## Timesteps
The following time steps are available:
* every hour from 0 to 54 hours
* every 3 hours from 57 to 120 hours 
 
## Update frequency
There are three lengths of model run, each with its own update frequency: 
* Nowcast: forecasts the next 12 hours and are at 0100, 0200, 0400, 0500, 0700, 0800, 1000, 1100, 1300, 1400, 1600, 1700, 1900, 2000, 2200 and 2300 UTC. 
* Short: forecasts the next 54 hours and are at 0000, 0600, 0900, 1200, 1800 and 2100 UTC. 
* Medium: forecasts the next 120 hours and are at 0300 and 1500 UTC.

## Archive length and latency

As of December 2025, the archive contains data from December 2023 onwards. Forecasts will continue to be available for at least two years from their data date.

The data is typically available 3-6 hours after the model run time.


## Technical specs
The data is available as NetCDF files. NetCDF (Network Common Data Form) is an interface for array-orientated data access and a library that supports the interface. It is composed of 3 components:
* variables store the data
* dimensions give relevant dimension information for the variables
* attributes provide auxiliary information about the variables or dataset itself

NetCDF is used within the atmospheric and oceanic science communities and is network transparent, allowing for it to be accessed by computers that store integers, characters and floating-point numbers.

Iris supports NetCDF files through reading, writing and handling. Iris implements a model based on the CF conventions, giving a format-agnostic interface for working with data.
