Radiosonde in Winter Sleet Near Tehran Outcrop

Indigo twilight blankets a rocky geology outcrop near Tehran as a gloved hand extends into the frame, gripping a weather balloon radiosonde. Fine sleet needles glint against the dark, wet stone and the metallic sheen of the instrument. Reflected light off nearby water casts a cool, silver glow across the scene, illuminating the texture of the heavy winter gloves and the intricate wiring of the device. Overcast skies weigh low, merging with the deep blue of the evening. The hand remains steady, fingers curled firmly around the sensor housing. One droplet of melting sleet rests on the edge of the white plastic casing, catching the faint reflected light before sliding down the wire.
