Description
Plains covered by gravel-dominated desert pavement in the Puna of Argentina have z0 of ~1 cm, likely representing a skimming flow regime above the closely spaced gravel particles. Roughness height locally may transition from that of skimming flow over the gravels to a roughness height that includes the effects of obstacles considerably larger than that of the gravel particles alone. Among large (>60 cm tall) megaripples, z0 is elevated beyond that of the gravels alone to values of 2 to 4 cm.
Notes
This upload consists of two files; an Excel file with all of the wind data collected in the Puna during the 2018 field trip (on five separate tabs, one for each anemometer, plus one ReadMe tab), and a pdf file with field photographs from each of the five study locations. The PSJ article to which these data are connected was accepted for publication on March 31, 2023.
