title: A Multi-Scale Algorithm for the NISAR Mission High-Resolution Soil Moisture Product

description: This study proposes a multi-scale soil moisture algorithm for the upcoming NASA-ISRO SAR (NISAR) mission to estimate high-resolution (200 [m]) soil moisture (the water content of the soil). The algorithm takes advantage of the high-resolution (~10 [m]) synthetic aperture radar (SAR) backscatter and coarse resolution modeled/reanalysis soil moisture products (~ 9 [km]) to create a high-resolution (200 [m]) soil moisture product at a global extent. The end goal of the algorithm is to remove dependencies on any complex modeling, tedious retrieval steps, or multiple ancillary data needs, and subsequently decrease the degrees of freedom to achieve optimal accuracy in soil moisture retrievals. The use of modeled/reanalysis soil moisture products with high temporal resolution gives an added advantage in reducing the temporal mismatch between the two different inputs used in the algorithm. In this study, the proposed algorithm is tested using L-band UAVSAR backscatter (σ°) data and Advanced Land Observing Satellite -2 (ALOS-2) SAR σ° as a substitute for the NISAR L-band SAR observations. The algorithm uses the L-band SAR σ° to disaggregate coarse resolution (~9 [km]) reanalysis soil moisture of the European Centre for Medium-Range Weather Forecast (ECMWF) to a high-resolution of ~200 [m] soil moisture product. The potential of the algorithm is demonstrated over three sites in different hydroclimatic regions of the world, such as India, the USA, and Canada. The high-resolution soil moisture estimates were compared with the in-situ soil moisture measurements available for three sites (North India, Southern California, and Carman, Manitoba, Canada). In North India, in-situ measurements are from paddy crops with high vegetation water content, the unbiased root-mean-square-error (ubRMSE) for the high-resolution soil moisture retrievals was found to be 0.036 [m3/m3] with a bias of -0.051 [m3/m3]. For the Southern California site, the validation statistics shows low ubRMSE of 0.027 [m3/m3] and a low bias of 0.016 [m3/m3]. At the Carman, Manitoba test site of Canada, where in-situ soil measurements were available for multiple crop types, the comparison shows that the ubRMSE for all the crop types lies below 0.05 [m3/m3] with an average bias of less than 0.07 [m3/m3]. The result confirms that the proposed algorithm meets the NISAR mission's accuracy goals, i.e., 0.06 [m3/m3] ubRMSE over areas with vegetation water content (VWC) below 5 [kg/m2]. Rigorous validation work will still need to be carried out in the future based on the availability of L-band SAR datasets and after the launch of the NISAR satellite.

title: Pickup ions from the breakup of Europa’s water ice surface

description: Jupiter’s moon Europa has a predominantly water-ice surface, modified by exposure to its17 space environment. Charged particles break molecular bonds in surface ice, dissociating18 water to ultimately produce H2 and O2 (Johnson 1990) and provide a potential oxygenation19 mechanism for Europa’s subsurface ocean (Chyba 2000). These species are understood to20 form Europa’s primary atmospheric constituents (Smyth & Marconi, 2006). While remote21 observations provide constraints on Europa’s atmosphere (Hall et al. 1995; de Kleer et al.22 2023), molecular O2 has solely been inferred from atomic O emissions. Europa’s atmospheric23 composition had never been directly sampled and model-derived oxygen production24 estimates ranged over multiple orders of magnitude. Here, we report direct observations of25 H2+ and O2+ pickup ions from the dissociation of Europa’s water-ice surface, confirming26 these species as primary atmospheric constituents. In contrast to expectations, we find the27 H2 neutral atmosphere is dominated by a non-thermal, escaping population. We find 12 ± 628 kg s -1 (2.2 ± 1.2 x 10 26 s -1 ) O2 are produced within Europa’s surface, less than previously29 thought, with a narrower range to support habitability in Europa’s ocean. This process is30 found to be Europa’s dominant exogenic surface erosion mechanism over meteoroid31 bombardment.

title: The NANOGrav 15-Year Data Set: Detector Characterization and Noise Budget

description: Pulsar timing arrays (PTAs) are galactic-scale gravitational wave detectors. Each individual arm, composed of a millisecond pulsar, a radio telescope, and a kiloparsecs-long path, differs in its properties but, in aggregate, can be used to extract low-frequency gravitational wave (GW) signals. We present a noise and sensitivity analysis to accompany the NANOGrav 15-year data release and associated papers, along with an in-depth introduction to PTA noise models. As a first step in our analysis, we characterize each individual pulsar data set with three types of white noise parameters and two RN parameters. These parameters, along with the timing model and, particularly, a piecewise-constant model for the time-variable dispersion measure, determine the sensitivity curve over the low-frequency GW band we are searching. We tabulate information for all of the pulsars in this data release and present some representative sensitivity curves. We then combine the individual pulsar sensitivities using a signal-to-noise-ratio statistic to calculate the global sensitivity of the PTA to a stochastic background of GWs with a minimum noise characteristic strain of 7×10^{−15} at 5 nHz. A power law-integrated analysis shows rough agreement with the amplitudes recovered in NANOGrav’s 15-year GW background analysis. While our phenomenological noise model does not model all known physical effects explicitly, it provides an accurate characterization of the noise in the data while preserving sensitivity to multiple classes of GW signals.

title: Impact of atmospheric cooling on the high-frequency submesoscale vertical heat flux

description: Recent simulations suggest that submesoscale motions with scales smaller than 30 km and frequencies greater than 1 day$^{-1}$ drive upward vertical heat transport. These simulations have prompted us to revisit the mechanisms that explain high-frequency vertical heat fluxes (VHFs) within the surface mixed layer (ML). Here, an idealized numerical simulation of a re-entrant channel flow with an unbalanced submesoscale thermal front is used to analyze the impact of surface cooling on high-frequency VHFs. Two types of simulations are analyzed: forced and unforced. The VHFs cospectrum analysis shows that surface diurnal cooling increases VHFs, reaching frequencies larger than 1 day$^{-1}$. However, the fastest-growing length scale of ML instabilities limits the extension of positive VHFs toward fine scales. Symmetric and gravitational instabilities are the main conduits producing ageostrophic high-frequency and small-scale structures, which in turn enhance upward VHFs across the diurnal frequency. A comparison between forced-idealized simulations with the KPP scheme and a realistic regional simulation in the frequency-wavenumber space, reveals that the two simulation types reproduce similar VHFs near the diurnal frequency. However, the realistic simulation displays higher VHFs than the forced-idealized simulation. This study emphasizes that surface diurnal cooling significantly impacts high-frequency VHFs. However, this impact is not sufficient to reach the high-frequency VHFs estimated in realistic submesoscale-permitting and tidal-resolving simulations.

title: Impact of Hunga Tonga-Hunga Ha'apai Volcanic Eruption on Stratospheric Water Vapor, Temperature and Ozone

description: Despite being rare, large volcanic eruptions can have a long-lasting impact on the chemistry, radiation, and dynamics of the stratosphere. This study attempts to quantify the changes in the stratospheric water vapour and its relationship to temperature and ozone observed from space-based Microwave Limb Sounder (MLS) observations during the submarine volcano eruption Hunga Tonga-Hunga Ha'apai that occurred on 15 January 2022. The most notable aspect of this eruption is the plumes, which are water vapour columns that reached higher altitudes (1 hPa (47.6 km)) than earlier eruptions. We discovered that the eruption injected a record amount of water vapour (6-8 ppmv) directly into the stratosphere from 38-10 hPa vertically, which is present even after 1 year. The majority of water vapour is confined to the Southern Hemisphere (SH) tropics, i.e. 30o S to 5 o N, and gradually descends to the SH polar latitudes over time. The WV from lower stratosphere reaches to mesospheric altitudes during January 2023. We quantify the impact of increased water vapour on temperature and ozone as well. Temperatures begin to fall during the month of March in the regions where there is an increase in water vapour. A ~5 K cooling occurs in July and August 2 as a result of the thermal adjustment to the extra water vapour IR cooling. Our analysis shows a decrease in ozone caused by an increase in water vapour. Significant variability is observed in all three parameters at 26 km compared to other levels. Further, we noticed that after 1 years of eruption, the water vapor , Temperature and Ozone didn’t reach the background values. It's possible that this unusual eruption produced a different atmospheric reaction than other significant volcanic eruptions that have been well investigated.

title: Comparing Complex Chemistry in Neighboring Hot Cores: NOEMA Studies of W3(H2O) and W3(OH)

description: This paper presents NOEMA observations of the neighboring hot cores W3(H2O) and W3(OH). The presence of two star-forming cores at different evolutionary stages within the same parent cloud presents a unique opportunity to study how the physics of the source impacts the chemistry. Through spectral analysis and imaging, we identify over twenty molecules in these cores. We have imaged the molecular emission, revealing several new structural features within these sources. Most notably, W3(OH) shows absorption in a “dusty cocoon” surrounded by molecular emission. These observations also reveal new extended emission features that are indicative of either a second outflow or a low velocity shock. From the information obtained herein, we have also constructed column density and temperature maps for methanol and compared this information to the molecular images.
