Measuring the Last Light_Ceilometer at High Altitude Cloud Physics Laboratory (HACPL), Mahabaleshwar.
As the sun settles at the horizon, its final rays align with a ground-based atmospheric observation system, momentarily merging nature and instrumentation. Against the warm hues of twilight, the radiometer stands poised to record subtle changes in temperature and humidity within the lower atmosphere. This quiet transition from day to night marks a critical period for boundary-layer evolution, when radiative cooling begins to reshape near-surface stability. The image captures how precision measurements often unfold during the most visually serene moments of the atmosphere.
