Applications for NCAR postdoctoral fellowships due 7 January: Appointments announced for 1993Š94 NCARÕs Advanced Study Program offers postdoctoral and graduate fellowships for research at NCAR. Applications for postdoctoral fellowships beginning in the summer or fall of 1994 are due 7 January 1994. The postdoctoral program provides an opportunity for recent Ph.D. recipients to continue their research in the atmospheric sciences and related fields and to develop expertise in new areas. There are eight to ten openings. Interested scientists with no more than four years of applicable experience past the Ph.D. level are eligible. The graduate fellowship program applies primarily to Ph.D. thesis work. For information on the application procedure, contact Barbara McDonald (see page 15).
