The High Asia Refined analysis (HAR*) is an atmospheric dataset generated within the frame of the WET project(Variability and Trends in Water Balance Components of Benchmark Drainage Basins on the Tibetan Plateau) financed by theBMBF CAME Programme (Central Asia - Monsoon dynamics and Geo-ecosystems) and also supported by the TiP Project. The HAR provides gridded fields such as temperature, precipitation and wind at 30 km resolution for Central Asia and 10 km for the Tibetan Plateau and surroundings (see Figure 1 - Model domains). The HAR intends to provide an estimate of the state of the atmosphere on an hourly basis during the last decade (starting in 2001). It can serve as a tool for studying climate variability and atmosphere related processes on the Tibetan Plateau, where other types of observations are scarce. The dataset will be updated and actualised regularly, either to provide new time periods or new/updated products.

Description

The dataset is generated using the atmospheric model WRF version 3.3.1 (Weather Research and Forecast model). The simulations are comprised from consecutive model runs of 36 h time integration, the last 24 h of model output providing one day of the final dataset. The model is driven by global observations (Final Analysis data from the Global Forecasting System with additional sea surface temperature input). Thus, it remains really close to observations while adding fine scale details and acting as a "smart" physically-based interpolator (without further assimilation of observations during the simulation time). The output of the model is post-processed into product-files: one single file per variable and per year at various aggregation levels (see Table 1).

Data Access

When using the data please refer to Maussion et al. (2014), and read carefully the disclaimer available here.

The field of applications for this dataset is rich and unexplored; in the first place, we demonstrate the feasibility of various applications in hydrological and glaciological modelling. We are also looking forward to new collaborations going towards a better understanding of atmosphere-related processes on the Tibetan Plateau. Please contact Julia Curio if you have any question.
