Fig. 3From: Characterization of atmospheric structures observed by a VHF MST-type radar in the troposphere over Santa Cruz, Costa RicaEcho layer results. Year-long statistics of atmospheric layers. One (L1), two (L2), or more than two (L3) echo layers were observed, and the percentage of time that each type of layering persisted within each month (relative to available radar time) is presented. The maximum value is reached during the dry-season months. The rainy season shows a decrease in the number of measurable layers. Error bars represent \(\pm \,1\) standard deviationBack to article page
