Environmental Fluid Dynamics - LUMPS Project

Spring 2023

SEB The purpose of this project is to model the Surface Energy Balance in a real city using LUMPS. The complete assignment for this first class project may be found on Canvas.

Data Sets

Part I: Radiation Modeling
  • Dugway Solar Radiation Data for validation of solar radiation model. Time is in UTC + 6.
  • BLLAST IOP 5 Radiation Data - These data were acquired above a European Larch forest on June 25, 2011. The location was 43°06'32.9" N, 0°21'32.1" E. For more information on the Boundary Late Afternoon and Sunset Turbulence (BLLAST) program, click here. Note that time is UTC time. The file type is a Matlab .mat file.

    • Part II: LUMPS model and evaluation

  • LUMPS Data set for August 20, 2005 at the Murray site.
  • To drive the model, you should use real solar radiation data acquired from Mesowest from August 20, 2005. You may consider using the MSI01 site August 20, 2005. This site was located at Sugarhouse Park 40.7233 N, -111.8591 W on that date.
  • Site location: 40 39.11 N; 111 55.19 W
  • Site Elevation: 1306 m
  • Site Albedo: 0.18
