Studies with ICESat-2 (ROSES 2022)

NASA  solicits  proposals  for  Earth science research using  observations  from  the Ice, Cloud,  and land  Elevation Satellite-2  (ICESat-2),  which was  launched on  September  15, 2018.  The Advanced  Topographic  Laser  Altimeter  System  (ATLAS)  instrument  on ICESat-2  is  the  most  advanced,  highest-resolution  altimetry  instrument  ever  placed in Earth  orbit.  ATLAS  is  a  photon-counting  lidar  with six  beams  and ICESat-2's  near-polar orbit  is  optimized to  enable it  to characterize elevation changes  in  Earth’s  polar  ice.  The mission collects  measurements  globally  –  away  from  the poles  –  particularly  to enable independent  determination of  vegetation  height,  but  also to support  research in hydrology,  oceanography,  atmospheric  sciences,  and  other  Earth  and applied sciences. Given the  exciting  scientific  opportunities  presented by  the mission's  unprecedented volume of  high-resolution  Earth observations,  for  proposers  to this  program  element NASA  requires  Open  Science  approaches  to  accelerate the  pace  of  scientific advancement.  NASA  also encourages  researchers  to  utilize emerging  methods  in scientific  data  analysis,  including  but  not  limited to:  machine  learning,  cloud-based processing,  and integration  of  ICESat-2  results  with advanced  Earth  system  models. Principal  Investigators  (PI)  of  the proposals  selected under  this  program  have additional responsibilities  as  members  of  the ICESat-2 Science Team  (I2ST).

Areas of Interest

This  program  element  solicits  proposals  to  pursue any  research topic  using  ICESat-2 observations  and  advancing  the  Earth  Science goals  articulated  in the  NASA  2018 Strategic  Plan  and  2020  SCIENCE  2020-2024:  A  Vision for  Scientific  Excellence  (both of  which may  be  found  at 34T 34T http://science.nasa.gov/about-us/science-strategy/ ). 

Two  categories  of  proposals  are  solicited.  ICESat-2  data  need to  be  central  for  either category:

(a)  Investigations  that  are using  ICESat-2  data to  address  major  needs,  gaps  or uncertainties  in  knowledge  in Earth Science  and especially  cryospheric  science  as identified,  for  example,  by  the latest  IPCC  report 34T 34T https://www.ipcc.ch/report/ar6/wg1/ the  Special  Report  on  the Ocean  and Cryosphere in  a Changing Climate https://www.ipcc.ch/srocc/ 34T 34T 34T , or  the  IARPC Arctic  Research  Plan https://www.iarpccollaborations.org/arctic-research-plan-2022-2026.html . 

(b)  Investigations  of  exploratory  nature.  Efforts  that  aim  to  extract  novel  information  from ICESat-2 data  or  are using  ICESat-2 to  investigate  parts  of  the  Earth  System  in a new way  are especially  encouraged.

Overall  priority  will  be  given to investigations  focused  on land  and sea ice  in  the  Earth's polar  regions.  Other  areas  of  Earth  science research  will  be considered at  a  lower  priority, but  NASA  anticipates  supporting  several  such  investigations.
