Dashed lines generator is a tool to automate, in few and easy steps, the generation of all types of dashed lines: it can be used to simulate the traffic signs standards; with the SKIN MODIFIER option it is extremely easy to manipulate the dashed lines created, changing their placement and orientation. With this script the user can have an interactive creation process of the dashed line, with a real time preview into the 3DS Max viewports.
Potential evapotranspiration (PET) is essential for understanding a range of climatic impacts from water resources to agricultural water demands, but future projections of PET are poorly understood, suggesting the need for multiple ensemble simulations to represent future uncertainty in PET. Stochastic weather generators are often used to generate multiple physically consistent timeseries of rainfall; however, no such model currently exists for generating plausible PET timeseries. Here we leverage a recently published dataset of hourly global PET at 0.1 resolution (hPET) to develop a new stochastic PET generator (stoPET). stoPET is designed to generate realistic timeseries of PET that capture the diurnal and seasonal variability inherent in historical hPET data. stoPET uses a sine function fitted to the average monthly diurnal cycle of hPET to generate parameters which are used to create a synthetic series of hourly PET over the globe at 0.1 spatial resolution. stoPET also incorporates four methods to account for potential future changes in atmospheric evaporative demand to rising global temperature, supporting flexibility in simulating various climate scenarios. These methods include: 1) user-defined percentage change of annual PET; 2) change in PET based on the historical trends generated from historical hPET and perturbed with randomly selected trend residuals; 3) change in PET based on a unit change in temperature; and 4) change in PET based on the progressive change in PET from the hPET trend. stoPET was initially evaluated at 12 locations spanning the globe across distinct arid and humid climates. Our evaluation showed a similar distribution from stoPET compared to hPET based on Normalized Root Mean Squared Error (NRMSE) ranging from 0.03 to 0.14 (R2 from 0.96 to 1.00) for humid regions and 0.06 to 0.18 (R2 from 0.67 to 1.00) for arid areas. Comparing the results with the Climate Research Unit (CRU) PET dataset, the NRMSE ranges from 0.09 to 0.37 (R2 from 0.59 to 1.00) in humid regions and between 0.19 and 0.25 (R2 from 0.38 to 1.00) in arid areas. The results indicate the newly generated PET effectively represents the daily diurnal cycle of PET and annual PET. This stochastic model is a flexible new tool for generating a high number of PET ensembles for future climate scenario analysis with low computational demand.
