The slow pace of federal research funding under Trump, coupled with his administration’s mass cancellations of existing grants, have led to severe underfunding of research. As another fiscal year under Trump comes to a close on September 30, NOAA, AHRQ, NSF are far behind in money awarded.

About 20 years ago, someone found half a deer when they arrived in the morning. The fences are higher now than then. The guards probably let the deer walk in through the gate but I am sure they would not allow a bear to wander in.

Russian oligarch Umar Kremlev footed the bill for hundreds of thousands of dollars of expenses at Donald Trump Jr.’s wedding, including renting out a private island. National security experts say it raises an urgent question: What motivated Kremlev to spend a fortune cultivating the connection?

The dates mentioned in the India Today article indicate that the person must have analyzed the NISAR track A98 data. On that track, the area they show as anomalous motion is on the west-facing wall of the range where A98 SAR is close to shadow, so I suspect poor quality offsets.

The ASF is looking at providing some on-demand processing, but I don't know what products they plan to support. The GOFF product requires substantial computing resources to process.
110
Dr. Eric J. Fielding, PhD @ericjfielding.bsky.social · 04/09/2026
I can't tell what is going on with the results shown in this India Today article. The range and azimuth offset maps look the same, which can't be correct. The standard NISAR L-band GOFF products are automatically processed for adjacent-in-time pairs, but the ISCE3 software can do longer intervals.

Dr. Eric J. Fielding, PhD @ericjfielding.bsky.social · 04/09/2026
Pixel offset tracking usually works over long time spans. Glaciologists have been using pixel offsets on SAR and optical images for many years to measure velocities of glaciers and ice streams. Offsets are stable against small surface changes and large displacements unlike InSAR.

The strong El Niño is expected to cause increased tropical storms in the East Pacific and decreased storms in the Atlantic, so this is not a surprise.

An El Niño-induced coastally-trapped Kelvin wave will likely raise water levels about 9-14 inches (relative to 1993-2025 averages) along the California coast in early October. Water temperatures will also increase. The sudden increase will be as much as “the entire climate change anomaly in one go”

All or almost all glaciers in the Himalayas have strong seasonal variations in their velocities.

Dr. Eric J. Fielding, PhD @ericjfielding.bsky.social · 02/09/2026
Yes, the observation plan over the Himalayas from May to November on descending tracks alternates between QP and DH mode acquisitions. This was requested by ISRO. It has the unfortunate effect of making every 12- day GUNW and GOFF pair be a mixture of DH and QP.

The NISAR incidence angles are large enough to avoid layover almost everywhere, even in the Himalayas.

Dr. Eric J. Fielding, PhD @ericjfielding.bsky.social · 02/09/2026
The DH (dual H-polarization) mode acquisitions, including 8-16, are dithered to fill in the transmit gaps, but the QP mode is not dithered so the products have gaps.
130
Dr. Eric J. Fielding, PhD @ericjfielding.bsky.social · 02/09/2026
The GOFF products are not mosaics but calculated from a single frame of the two RSLC products. The along-track strips of no data are due to the transmit gaps in the QP (quad polarization) mode acquisition of 8-28.
110
Dr. Eric J. Fielding, PhD @ericjfielding.bsky.social · 02/09/2026
If you are asking about the strange area of wild offset values in the GOFF that spans the event, then that is where the pixel cross-correlation calculation did not find a good match because the surface changed too much. It is a low resolution change map.
