Song Woods Hole Oceanographic Institute, Woods Hole, Massachusetts Abstract. Characteristics of the long-term variation of daytime (0600-1600 hours MLT) ELF-VLF emissions are examined, using 7 and 4 years of digital data obtained at a conjugate pair of stations, Syowa in Antarctica and Husafell in Iceland. 1. Introduction Long-term observations are necessary to characterize and understand the solar influence on various phenomena. 2. Level 1 Head Ragged Right With a Flush Left Wraparound Line 2.1. Level 2 After Level 1 Head Diurnal variations of emission occurrence are examined using data observed at two geomagnetic conjugate stations. 2.1.1. Level 3 head. Include at least two level 3 heads if any are used.

This is a broadside caption, which must fit within 17.3 cm (6 13/16 inches, 41 picas). Set the left and right margins at 0.75 inch for the maximum width allowed for a broadside caption. Make sure that the font size is 9.7 CG Times and that the line spacing is 0.94 inch to match AGU caption style. Turn justification on, and do not forget to put the word "Figure" or "Plate" and a period in bold, with two spaces between the period and the beginning of the caption text.
