    • note
    • For mass balance within the 1992-2002 time period, the following estimates have been published: +11 ± 3 Gton/year for 1992-2002 (3), -46 Gton/year for 1993/4 - 1998/9 (21), -72 ± 11 Gton/year for 1997-2003 (2), and -83 ± 29 and -127 ± 29 Gton/year for 1996 and 2000, respectively (5). If the correction for firn compaction used in the radar altimeter analysis (3) is applied to the airborne altimeter estimates (2, 4, 21), the difference between the two approaches is reduced by about 23 Gton/year, as reflected by revised airborne values of -4 to -50 Gton/year for 1993 to 1999 (4).

    • note
    • For the 1990s, we used the small 11 Gton/year mass gain from (3) and noted that the negative balances discussed in (7) either would give significantly less negative changes than 113 Gton/year or would give positive changes, in contradiction to the evidence for increases in melt and glacier accelerations. Also, our 113 ± 17 Gton/year is in good agreement with the change in mass flux of 117 Gton/year from 1996 to 2005 from radar interferometry (5).
