It is distributed in a simplistic manner in most glacier melt models by using constant linear lapse rates, which poorly represent the actual spatial and temporal variability of air temperature. In this paper, we test a simple thermodynamic model proposed by Greuell and Böhm in 1998 as an alternative, using a new dataset of air temperature measurements from along the flowline of Haut Glacier d’Arolla, Switzerland. The unmodified model performs little better than assuming a constant linear lapse rate. When modified to allow the ratio of the boundary layer height to the bulk heat transfer coefficient to vary along the flowline, the model matches measured air temperatures better, and a further reduction of the root-mean-square error is obtained, although there is still considerable scope for improvement. The modified model is shown to perform best under conditions favourable to the development of katabatic winds – few clouds, positive ambient air temperature, limited influence of synoptic or valley winds and a long fetch – but its performance is poor under cloudy conditions.","lang":"eng"}],"intvolume":" 54","status":"public","title":"Suitability of a constant air temperature lapse rate over an Alpine glacier: Testing the Greuell and Böhm model as an alternative","_id":"12642","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","oa_version":"Published Version","keyword":["Earth-Surface Processes"],"scopus_import":"1","article_processing_charge":"No","day":"01","page":"120-130","article_type":"original","citation":{"ama":"Petersen L, Pellicciotti F, Juszak I, Carenzo M, Brock B.

In this paper, we test 13 clear-sky parameterizations combined with seven cloud corrections for all-sky atmospheric emissivity at one location on Haut Glacier d'Arolla. We also analyze the four seasons separately and conduct a cross-validation to test the parameters’ robustness. The best parameterization is the one by Dilley and O'Brien, B for clear-sky conditions combined with Unsworth and Monteith cloud correction. This model is also the most robust when tested in cross-validation. When validated at different sites in the southern Alps of Switzerland and north-western Italian Alps, all parameterizations show a substantial decrease in performance, except for one site, thus suggesting that it is important to recalibrate parameterizations of incoming longwave radiation for different locations. We argue that this is due to differences in the structure of the atmosphere at the sites. We also quantify the effect that the incoming longwave radiation parameterizations have on energy-balance melt modeling, and show that recalibration of model parameters is needed. Using parameters from other sites leads to a significant underestimation of melt and to an error that is larger than that associated with using different parameterizations. Once recalibrated, however, the parameters of most models seem to be stable over seasons and years at the location on Haut Glacier d'Arolla.","lang":"eng"}],"issue":"8","quality_controlled":"1","oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1002/jgrd.50277"}],"language":[{"iso":"eng"}],"doi":"10.1002/jgrd.50277","month":"04","publication_identifier":{"issn":["2169-897X"]},"publication_status":"published","publisher":"American Geophysical Union","year":"2013","date_updated":"2023-02-21T10:10:46Z","date_created":"2023-02-20T08:17:34Z","volume":118,"author":[{"first_name":"I.","last_name":"Juszak","full_name":"Juszak, I."},{"last_name":"Pellicciotti","first_name":"Francesca","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","full_name":"Pellicciotti, Francesca"}],"extern":"1"}]
