High Resolution Deterministic Prediction System (HRDLPS)

Overview

HRDLPS is a 2.5-km high resolution land surface predicition system that produces high-resolution medium-range forecasts of surface and near surface variables, and provides high quality input fields to operational hydrological systems. The system uses CaLDAS-Sat analyses for initial conditions and forcing fields from HRDPS and GDPS. HRDLPS generates the necessary input fields for the Deterministic Hydrological Prediction System (DHPS) .

What is the spatial resolution and coverage of this data?

HRDLPS is run on a 2.5-km national grid.

What is available?

What is the timestep and time period covered by this data?

HRDLPS is run every 12 hours (00 and 12 Z), and currently produces hourly forecasts up to 6-days (144h) into the future.


What are the outputs from this product?
HRDLPS produces hourly forecasts with lead times up to 144h of near-surface, surface, and sub-surface variables such as:
  • 1.5-m temperature and dewpoint, 10-m wind
  • Surface temperatures (bare ground, vegetation, snow)
  • Soil mositure
  • Hourly hydrological fluxes (i.e. subsurface runoff, subsurface lateral flow, and drainage.
