We are well into February and now both Software Development Scientists have rolled up their sleeves and are working hard at the following projects:

UNRESP: The CALPUFF workflow has been investigated and how to get precise reference data for Nicaragua Region of Interest (around the Masaya Volcano) has been established. Next is the investigation of whether there is an alternative to using the Meteorological Data that is currently sourced from ECMWF. (An example of the likely output is map_concrec010048)

Air Quality Living Lab: A web site has been provided for the scientists to upload data from CPC devices used to detect Air Quality around Campus. It subsequently displays the information against a Google Map background. The track is gleaned from GPS logging during the walkabout. (http://sustainability.leeds.ac.uk/the-living-lab/airquality/)

AfriCultRes:: A preliminary analysis of the code (GLAMv3) has been undertaken and already a prototype with modifications is under testing; it promises a “huge” computational improvement on the existing implementation. The time for the calculations is greatly reduced and the memory requirement is also reduced (thus queuing for a large memory computational node is not necessary).

JWCRP Stage2 (Chemistry processes): This project has been in hiatus since the work on the aerosol sub-processes was completed in vn10.8. Now with (vn10.9 and 11.0) this project will provide significant changes to the UKCA code to enhance the computational performance; initially this will be through “cache-blocking” style of additional nested do loop; this will be followed by adding OpenMP regions around the loops over columns of atmosphere.

CRESCENDO: There are a couple of aspects currently being addressed. (a) using the CISTools for processing the output of the UM, Satellite (MODIS) and In-situ AOD data (AERONET); (b) contributing to the evaluation work package and helping with the configuration of UK-ESM runs that will provide data for the evaluations. (https://www.crescendoproject.eu/)

Decoding MeteoSat archives: One aspect of this work has been installing and developing tools to extract specific data from MeteoSat BUFR files. The original BUFR tools are being superceded by “ecCodes”, an ECMWF product (similarly it takes over the GRIB api activity).

Below is an example ‘full disc’ image from Meteosat-10, showing Brightness Temperature from the Infrared 10.8 micron Channel:

UKMO Unified Model on ARC3: there is a continued effort to get the UM running on ARC3 to support any local researcher who needs to do runs of the model locally. Typically this would be a research project that does not have access to Monsoon or Archer. Good advice and guidance is being provided by NCAS CMS (http://arc.leeds.ac.uk/ and cms.ncas.ac.uk)
