Spartacus Ep 8

[Destini Armstrong]

Ihave an existing application built using Hybris and jsp. We need to move some static pages to Bloomreach and the application will be made headless. We are using the Spartacus storefront for the same. Spartacus will be integrated to Hybris and for pages that are not present in Hybris, we need to make a call to Bloomreach from Spartacus to get those pages. For that, I am trying to integrate Bloomreach to Spartacus. Can someone help me with steps or link to steps to complete integration for the same. Any lead is appreciated. Thanks

I have no knowledge of Spartacus or Hybris. From the bloomreach side, it depends on what you want brxm to deliver. Do you want a complete html web page, or do you want json response for your frontend? Or something else?

I saw that the npm package talks to only page model api. But in my case, I want to talk to delivery api as I want to get documents created inside Bloomreach.

I need to retrieve document from bloomreach and render it between header and footer in my Spartacus application.

Using api approach, will have to write html/css on our own, It defeats the purpose of using Bloomreach for CMS.

We need to create pages/components in bloomreach and view them in our app. How can we achieve it?

Three-dimensional radiative effects are potentially important in anumber of environmental modelling contexts, but traditional approaches(e.g. Monte Carlo) are far too slow to incorporate into large-scalemodels. SPARTACUS (the SPeedy Algorithm for Radiative TrAnsfer throughCloUd Sides) is an algorithm that can fill the gap. It takes as astarting point the two-stream equations, which take as input a 1Ddescription of the atmosphere and produce a profile of upwelling anddownwelling fluxes. SPARTACUS divides each layer of the atmosphereinto one, two or three regions (which may represent clouds, vegetationelements or buildings) and explicitly computes the horizontaltransport of radiation between regions. However, the shape of theregions and their vertical overlap is described statistically, soSPARTACUS avoids the computational cost of an explicit 3D descriptionof the scene.Application to cloudsThe original SPARTACUS application wasclouds. Hogan andShonk (2013) introduced the modified two-stream equations in theshortwave, and showed that the only quantity required to describe theshape of the regions was the length of the interface betweenthem. Schferet al. (2016) extended the scheme to the longwave and demonstratedthe need to account for cloud clustering and the fractal nature ofclouds. This workwas highlightedbyEOS. Hoganet al. (2016) introduced a more elegant solution method usingmatrix exponentials, and performed a broadband evaluation of theshortwave and longwave schemes for a cumulusscene. Hogan etal. (2019) performed a detailed shortwave evaluation using MonteCarlo calculations on a large number of scenes, which revealed the importance of the "entrapment" mechanism.Our ultimate aim is to incorporate a validated scheme forrepresenting 3D effects into a weather/climate model and to computethe impact of 3D effects on a global scale. SPARTACUS is alreadyavailable as an optionin ecRad(Hogan and Bozzo2018), the radiation scheme used in the ECMWF weather forecastmodel, and preliminary results are shown in the talks below.Please note: Comparison to explicit Monte Carlo calculations reveals that the longwave component of SPARTACUS can significantly overestimate the 3D effect of high clouds. This is believed to be due to one of SPARTACUS's assumptions (that radiation is evenly distributed horizontally within each region of each layer) being inaccurate in optically thin clouds when the source of the radiation is the clouds themselves. We are considering alternative formulations to address this conceptual issue, but for the moment SPARTACUS is not recommended for quantitiative calculations in the longwave. This does not apply the urban/vegetation case described below.Application to vegetation and urban areasIn temperate forests, 3D radiation transport between trees and the clear regions between them can have a significant effect on the albedo of the scene and the amount of absorbed photosynthetically active radiation. Hogan et al. (2018) have demonstrated the accuracy of SPARTACUS via comparison with reference Monte Carlo calculations for the scenes of theRAMI4PILPSintercomparison study. The Matlab code used in this study isavailable below.Hogan (2019b) adapted SPARTACUS to cities, including the option to move from a 2- to an N-stream representation of the radiation field. The resulting "SPARTACUS-Urban" model can represent realistic urban geometry, buildings of different height, street trees and atmospheric absorption, emission and scattering. It exploits the finding of Hogan (2019a) that wall-to-wall separation distances in urban environments tend to follow an exponential distribution. Stretton et al. (2022) evaluated the shortwave fluxes computed by the model against explicit calculations by the DART model in which every building is represented, while Stretton et al. (2023) evaluated its longwave capabilities.The SPARTACUS-Surface radiation scheme (GitHub) is an open-source Fortran 2003 implementation of the SPARTACUS vegetation and urban radiative transfer algorithms..PublicationsOriginal shortwave scheme for clouds
