Core Components of an Off‑Grid System Every robust off‑grid installation hinges on four essential building blocks: Energy Generation: Solar panels, small‑scale wind turbines, or micro‑hydro units convert natural resources into DC electricity. ...
Understanding the Impact of Map Projections on Polygon Size: A Comparison of OpenStreetMap and Google Earth. Why if you draw a polygon in a OpenStreetMap has a different size than in Google Earth? The difference in size between a polygon drawn in OpenStreetMap and the same polygon in Google Earth can be attributed to the use of different map projections. Map projections are ...
What is a reanalysis? Reanalysis integrates model data with observations worldwide to create a globally comprehensive and consistent dataset through the application of physical laws. This process, known as data assimilation, mirrors the methodology employed by numerical weather prediction centers. At regular intervals (e.g., every 12 hours at ECMWF), a previous forecast is merged with newly ...
At Vortex we use WRF model to produce high-resolution wind estimations. The three atmopheric reanalysis (ERA5 from ECMWF, MERRA2 from NASA and CFSR from NCEP) provides meteorological variables as wind horizontal components, temperature, pressure, humidity, etc. which are used as initial and boundary conditions for our simulations. However, the model also requires additional datasets for ...
