FESSTVaL Campaign

In 2020 and 2021 this HErZ branch is active­ly par­tic­i­pat­ing in the mea­sure­ment cam­paigns FESST@home and FES­ST­VaL (Field Exper­i­ment on Subme­soscale Spatio-Tempo­ral Variabil­i­ty in Linden­berg, http://fesstval.de/). FES­ST­VaL is orga­nized by all groups of the Hans-Ertel-Cen­tre for Weath­er Research and sup­port­ed by DWD with addi­tion­al instru­men­ta­tion com­ing from var­i­ous nation­al and inter­na­tion­al groups. With­in our con­tri­bu­tion, we plan to gain insights for mea­sur­ing and char­ac­ter­iz­ing gusts and night-time low-lev­el jets from remote sens­ing obser­va­tions. This infor­ma­tion is then uti­lized to improve the gust rep­re­sen­ta­tion of cur­rent and upcom­ing high-res­o­lu­tion reanaly­ses. Fur­ther, the dense net­work of sur­face mea­sure­ments as well as pro­fil­ing obser­va­tions will be used to bet­ter under­stand the impact of bound­ary lay­er and sur­face het­ero­gene­ity on local scales and to bet­ter rep­re­sent these het­ero­geneities in sub-kilo­me­ter scale region­al reanaly­sis by employ­ing a data-assim­i­la­tion approach.
