Overview

Modelling and emission activities in CAMS apply a wide range of land use and land cover (LULC) data sets.  A summary can be found in this document:

Summary of discussed points:

  • Planned IFS (NWP/Carbon Cycle) developments
    • Move from to GLCC1.2 to ESA-CCI data 
    • Improved disaggregation into high and low vegetation LAI
    • NRT LAI data assimilation developments are planned as COCO2 effort 
    • Potential to include fire / burnt area surface class in collaboration with CAMS
  • Strong interest by global and regional AQ groups in availability of NRT LAI data
  • Urban tile will be important input for IFS-CAMS (e.g. dry deposition) 
  • Online modelling of biogenic VOC emissions modelling requires more detailed PFT breakdown (e.g.  for isoprene) and also PTF -specific LAI information in IFS 
  • GFAS development and operational configuration uses different LULC data sets
  • Steps for improved harmonisation of global LULC data in IFS / CAMS
    • Be aware of the specific needs for different processes / projects
    • Agree to upgrade together to ESA-CCI or Copernicus-Land data sets
    • Introduce sub-classification where needed
    • Share cross-walking tables
