There is a growing concern regarding the imminent gap in satellite polar altimetry, which is likely to occur in the latter half of this decade. Therefor, a letter has been prepared to raise awareness of the situation with sufficient time for agencies to make preparations for mitigating the gap with some alternative provision.

The letter will be a community statement which outlines (i) the importance of Polar Altimetry, (ii) the major risk of an imminent gap in this capability, and (iii) the need to consider mitigation meausre as a matter of emergency.

 We are reaching the polar community for its support, and therefore we ask for your support by adding your signatures to the letter, here:
