• Hydrologic models were used to assess remotely sensed surface water estimates.
• The accuracy of satellite surface water estimates diminished for waterbodies < 2 ha.
• Vegetation reduces accuracy of surface water detection, especially during wet years..."

simulation year of 30th March 2015 - 29th March 2016, for (a)
the ‘present’ surface water coverage, and (b) the ‘present’ - ‘past’
dierence. The black boxes indicate areas discussed in the text,
clockwise from north to west: the Aralkum, the Kyzylkum, the
Karakum, and the Garabogazköl Basin.

maps - Yearly mean PM10 values (a) from dust emitted by the Aralkum. The WHO’s guidelines recommend upper limits of 15 micro grams / m³ on the yearly average, and 45 micro grams / m³ on the daily average. Plotted in panel (b) are the numbers of days which exceed this daily average threshold of 45 micro grams / m³

a Time series of near-global (60° S–70° N) mean SST anomalies, Niño 3.4 (black), the Pacific Decadal Oscillation (PDO) index with 1-year smoothing (blue), and a North Atlantic tripole index (brown). Negative PDO corresponds to anomalous positive SSTs in the central N. Pacific. b Near-global ERA5 SST trend, 1980–2022, °C/yr. c Correlation between the Niño 3.4 index and GRACE/FO d(TWS)/dt, the latter lagged 2 months with 4-month smoothing applied. d Correlation between the PDO index and GRACE/FO TWS, 3-month smoothing applied

Map of mascons in which the GRACE/FO era minimum terrestrial water storage occurred after the start of 2015, color coded for the year of that minimum. The time series plotted in Fig. 2 is averaged over the South American region delineated in red

Comparison of ERA5-Land, GRACE/FO, and complementary observations: a deseasonalized time series of global land average (60S-70N) TWS anomalies (mm) from GRACE/FO, ERA5-Land, and ERA5 vertically integrated moisture flux convergence, b ERA5-Land precipitation (P), evapotranspiration (ET), and runoff (RO), c same as b but for GPCP P, GLEAM ET and G-RUN RO. Units in b and c are mm d−1, d 2003–2022 trend in ERA5-Land P-ET, e Same as d but for GPCP v3.2 P—GLEAM 3.6a ET. Units in d and e are mm d−1/yr. All anomalies are relative to the 2003–2022 monthly resolved climatological mean

TWS trends (mm/yr) over the period 2003–2022 in a GRACE/FO and b ERA5-Land; and c correlations of monthly TWS anomalies between GRACE/FO and ERA5-Land. Ice sheets and areas of significant glacial extent have been masked

Maps showing the improved alignment possible in the 3D Hydrography Program by using hydrography data derived from high-quality elevation data from the 3D Elevation Program (3DEP). The example maps show topography and streams near the border between Skagit and Snohomish Counties in Washington.

map - Example of hydrography derived from 3DEP lidar data for a section of the Marshyhope Creek near Federalsburg, Maryland.

Block diagram showing elevation data being collected over natural and human-made environments. Built using high- resolution 3D Elevation Program and 3D Hydrography Program data, the 3D National Topography Model (3DNTM) will incorporate other critical landscape information such as landcover, structures, transportation, and geology to inform a comprehensive understanding of the landscape to enable data-driven decisions and science. The 3DNTM aspires to augment today’s airborne-acquired elevation data with data acquired from a variety of platforms including satellite, drone, and potentially others. Hydrography data for lakes, rivers, and reservoirs will be derived from that elevation data to form an integrated representation of the landscape that can be connected with other water features such as wetlands and groundwater.
