ACE White Papers submitted to 2017 Decadal Survey

These RFI responses were primarily drawn from material in previous ACE reports and workshops, as well as from a whitepaper that emerged from a community workshop that was held at NASA Ames Research Center in May of 2014. The workshop report is entitled "Outstanding Questions in Atmospheric Composition, Chemistry, Dynamics, and Radiation for the Coming Decade". The word document can be retrieved from this page.

Request for Information #1

In preparation for initiation of the 2017-2027 NRC Decadal Survey in Earth Science and Applications from Space, the Space Study Board of the U.S. National Academy of Sciences has issued an Initial Request for White Papers. This RFI was issued to inform the initial organization and structure of the committee and panels that will conduct the survey, as well as to provide direct input to the work of those groups. In order to capture the breadth of the ACE science objectives, the aerosol/cloud/ecosystem leadership of the ACE Science Study team submitted 3 separate RFI responses on November 2015:

  1. An overarching, interdisciplinary response that articulates the ACE vision of interconnected Aerosol/Cloud/Ocean Ecosystems science questions. This white paper stresses the fact that the science questions that drove the 2007 DS to propose ACE are still valid today. It addresses the readiness issue by mentioning the technological/scientific advances of the ACE Study effort in the last 10 years.

  2. An aerosol response focused on the Direct Aerosol Radiative Forcing (DARF) science questions, and by necessity the aerosol Sources, Processes, Transport & Sinks (SPTS) science questions (see Aerosol STM).

  3. A response stressing the cloud-aerosol science questions (from elements in the ACE cloud & aerosol STM), focusing on shallow, non-precipitating clouds, radiative effects, etc. The goal here is to complement the CaPPM white paper that focus on precipitation and water cycle aspects.

For reference, we are also including a draft white paper from the Cloud and Precipitation Measurement (CaPPM) group. The CaPPM concept addresses much of ACE cloud-precipitation science objectives, and amplifies them with additional precipitation and hydrological cycle specific questions. Likewise, the white paper submited by Ocean Biology and Biogeochemistry community addresses ACE's ocean ecosystem objectives.

Request for Information #2

The 2017-2027 NRC Decadal Survey steering committee came out with a Second Request for Information that was due on May 15th, 2016. While the first RFI asked for overarching science and applications targets, this second time around the committee requested information about measurement concepts capable of addressing these targets. The ACE science study team submitted 4 responses related to a) Direct Aerosol Radiative Effects (DARF), b) aerosol-cloud interactions, c) ocean ecosystems objectives, as well as d) a constellation build around PACE to advance aerosol, cloud, precipitation and ocean ecosystem science. Another paper describing a measurement concept that addresses ACE's cloud-precipitation objectives were submitted by the Cloud and Precipitation Process Measurement (CaPPM) group.
